Data relay apparatus
A first receiver receives an activation signal from a first network and gives the activation signal to an input side of a second transmitter via a first connection line; thereby, the activation signal is sent out via the second transmitter to a second network. Thus, the activation signal is not directly transmitted from the first network to the second network; instead, the activation signal is transmitted by using conversion functions of the first receiver and the second transmitter. This configuration can prevent occurrence of distortion or attenuation in the activation signal. The activation signal from the first network thus enables ECUs belonging to the second network to be activated certainly without delay. |

Capacitor leakage compensation for PLL loop filter capacitor
An output portion of a charge pump receives control signals from a phase frequency detector and in response outputs positive current pulses and negative current pulses to a loop filter. A current control portion of the charge pump controls the output portion such that the magnitudes of the positive and negative current pulses are the same. Within the current control portion there is a “Charge Pump Output Voltage Replica Node” (CPOVRN). The voltage on this CPOVRN is maintained to be the same as a voltage on the charge pump output node. A capacitor leakage compensation circuit indirectly senses the voltage across a leaking capacitor of the loop filter by sensing the voltage on the CPOVRN. The compensation circuit imposes the sensed voltage across a replica capacitor, mirrors a current leaking through the replica, and supplies the mirrored current in the form of a compensation current to the leaking capacitor. |

Low-power and all-digital phase interpolator-based clock and data recovery architecture
The proposed invention is about an improved method for serial-in and serial-out transceiver applications. The proposed system includes a dual loop phase locked loop (PLL) architecture having a PLL and a phase rotator (PR)-based delay locked loop (DLL). An advantage of this architecture is that a single PLL offers decoupled bandwidths; a wide jitter-tolerance (JTOL) bandwidth for receiving data and a narrow jitter transfer (JTRAN) bandwidth for the data transmission. Thus, the amount of jitter at the output can be substantially reduced relative to the input while offering sufficient jitter tracking bandwidth. Also, this architecture is suitable for low-power applications since a phase shifter in the data path, which is one of the most power-hungry blocks in conventional DPLL designs, is not required. |

Semiconductor device incorporating a power on circuit
A semiconductor device which makes it possible to reduce a wasteful standby time at power-on is provided. In this semiconductor device, a reset of an internal circuit is canceled as described below. When a data signal stored in a storage section is at “0,” the reset is canceled by bringing an internal reset signal to the “H” level when a relatively short time has passed after the rising edge of a power on reset signal. When the data signal is at “1,” the reset is canceled by bringing the internal reset signal to the “H” level when a relatively long time has passed after the rising edge of the power on reset signal. Therefore, a wasteful standby time at power-on can be reduced by writing the data signal logically equivalent to the rise time of supply voltage to the storage section. |
