44 Method for variably adjusting output impedance of output driver circuit JP2002218315 2002-07-26 JP2003069416A 2003-03-07 HUMPHREY GUY HARLAN
PROBLEM TO BE SOLVED: To provide an output driver circuit that has a higher output impedance rage with a fewer control lines while preventing occurrence of a spike with the output impedance on the signal pad. SOLUTION: A binary weighted thermometer code is employed to adjust the output impedance of a variable impedance output driver circuit. The driver circuit includes an impedance network comprising a plurality of resistive devices each programmably electrically connectable in parallel between a first voltage source and the signal pad. The resistive devices are partitioned into a plurality of sets. A first set of the resistive devices may be programmed in a binary incremental manner to electrically connect one or more of the resistive devices in the first set between the first voltage source and the signal pad. Only if all of the resistive devices in the first set are activated may a second set of the resistive devices be started. Additional sets of the resistive devices may be likewise programmed.

PROBLEM TO BE SOLVED: To avoid such a situation as an output multi-bit digital signal is fixed at a full-bit (a maximum value) even if a one-bit signal exceeding a maximum modulation factor is inputted when a converter is constituted, which samples down the one-bit signal by using a decimation filter with the specified maximum modulation factor and converts the signal into the multi-bit signal and to attain an average level rising. SOLUTION: A converting part 7 converts a one-bit digital signal D1 from a reproducing signal processing part 4 into a multi-bit digital signal DM and attenuates it. A level detecting part 10 detects the level of the multi-bit digital signal DM converted by the converting part 7. A level control part 12 controls the level of the multi-bit digital signal DM outputted from the converting part 7 not to exceed a full bit according to the level detected by the level detecting part 10.

バス上で送信されるべき現在の値がバスの前の状態と比較される、相互接続バスを交差するように信号を送信するための符号化小振幅方式。 ビット反転の数がNよりも多いとき、Nはバスの幅であり、反転された信号値を送信するための決定がなされる。 さらに、バス値が反転されているか否かを示すために受信機に「反転」信号も送られる。 次いで、これらの符号化された値は小振幅値に変換され、送信される。 このようにして、相互接続で消費されるエネルギーが最小限であることを保証することができる。 この方策は相互接続での遷移の確率を減少させるだけでなく、従来技術に比べて非常に大きなエネルギー減少を達成するように小振幅値だけを送信する。
51 Time stamping system JP29345598 1998-10-15 JPH11191168A 1999-07-13 RUST ROBERT A
PROBLEM TO BE SOLVED: To reduce the size of a memory map by reading respective time stamps, individually determining whether or not respective time stamps are advanced, and individually advancing the respective time stamps in response to the decision means. SOLUTION: This system waits for an update cycle to start (step 5) and updates respective time stamps after a timer for an update cycle ends. Random numbers are generated for the respective time stamps (step 10) and then the time stamps are read out of their locations in the memory (step 20). To advance time stamps, a minimum run length of 0's of the random numbers is determine by using an index table and after the random numbers are compared with the index table (step 30), it is determined whether or not the time stamps are advanced (step 40). When the random numbers match the minimum number of 0's being advanced, the time stamp is advanced. COPYRIGHT: (C)1999,JPO

PURPOSE: To hardly generate a large distortion even when a transmission line error occurs. CONSTITUTION: Representative vectors z1i , z2j are selected from code tables 1, 2 respectively, multipliers 21, 22 multiply them by weighting factors w1 , w2 , a synthesis section vector-synthesizes the multiplied vectors z1i w1 , z2j w2 , and a controller 6 selects the combination of z1i , z2j to minimize the distance (distortion) between the synthetic vector yi ,j and the input vector (x). The weighting factors W1 , W2 have the same number of elements as the element number of the vector z1i , and the weighting factors w1 , w2 are selected so that the sum of both diagonal matrixes of the w1 , w2 becomes the constant times the unit matrix when the weighting factor matrixes contain these elements as diagonal elements.
53 Multiple resonance type tunneling circuit for positive digit range-4 base-2 to binary conversion JP14524694 1994-05-24 JPH07147536A 1995-06-06 ARUBAATO EICHI TADEIKEN
PURPOSE: To constitute a multilevel logic circuit by using a multi-peak type resonance tunneling device by making the binary work of an L-value show the same numeric value as that of a range N when that of the range N is impressed at the input terminal of a voltage divider. CONSTITUTION: The input of a positive digit range-4 base-2 to binary converter is the word S of a range-4 and base-2 which is a positive number and the word S is composed of numbers S0 -S4 (S0 : the least significant digit). The digits are decomposed by means of range-4 base-2 to binary converters 50. The output of each converter 50 is composed of a two-digit binary word and the word has the same value as that of an inputted multilevel digit (where, a carry digit C is the most significant binary digit and W is the least significant digit). An adding circuit 52 generates the digit in an intermediate area 3 by adding the outputs C and W from adjacent converters 50 to each other and the digit is decomposed by means of another converter 50. A decomposing stage 53 generates a word of a range-4 and base-2 of W-1 digit width and a binary bit to the word which is the digit width of the W.
54 Binary coding method and increasing/decreasing method with nearly uniform rate of change with respect to binary element JP31303191 1991-11-02 JPH06120839A 1994-04-28 JIYATSUKU BURUJIE; MAAKU JIROORU
PURPOSE: To provide a binary coding method for digital data that produces a uniform or an almost uniform mean change rate and to produce a minimum number, that is, a number equal to or close to 1 with respect to a change in a binary element. CONSTITUTION: The coding is conducted in three stages, a value is coded in a 1st reference field 11, the value is coded in a replacement field 12, and finally the replacement field is rotated (23). The procedure begins with a Euclid division 21 for a total number N by a number nR, for each value coded in the replacement field. Two values Q, R are obtained corresponding to the quotient and the residue of the division. The value R is coded by a coding module 22 according to a selected coding logic. The binary series obtained in this way is rotated (23), and the magnitude of the rotation is a function of the value Q. The binary series obtained after the rotation is assigned to the replacement field 12. COPYRIGHT: (C)1994,JPO
55 D/a converting circuit JP11326289 1989-05-02 JPH02292916A 1990-12-04 KIMURA SHIGENOBU
PURPOSE: To perform the converting operation of good linearity by providing a means which inputs a digital signal, a means which converts a pulse wave, a buffer means, and a means which outputs the output of this buffer means through a low pass filter. CONSTITUTION: The digital signal is inputted to an oversampling digital filter 11 and is subjected to interpolating operation to become data required for a noise shaping circuit 21 of the succeeding stage and is outputted as data X. Data X is converted to a PDM signal by the circuit 21 and is outputted as a quantized signal Y, and the signal Y is supplied to an LPF 32 through an optical coupling circuit 31. Since the input and the output of the circuit 31 are electrically insulated from each other, noise transmission to the LPF 32 is stopped though switching noise is generated in the filter 11 and the circuit 21. Then, the integral value of the signal Y, namely, an analog output corresponding to data X is obtained from the LPF 32. Thus, noise is prevented from being mixed with the analog output.
