A videoamplifier including at least one transistor amplifying circuit (T₁, T₂, 10, 18, 20) which is designed in such a way that the transistors (T₁, T₂) will exhibit a linear characteristic in a range of small variations of the input signal (Vi) and a hard switching characteristic in response to large input signal variations. Due to this circuit design, the output signal (Vo) will, in general, be proportional to the input signal (Vi) but will be able to respond more quickly to a sudden increase of the input signal. |

大信号出力ブースト段を備えた小信号増幅器は、第1の電源レールと第2の電源レールとの間に接続されている(vIII)。 小信号増幅器は、第1および第2の入力信号(INP、INM)を受け取り、負荷をドライブする出力接続点に出力信号を提供している。 小信号状態下では、出力信号は差動電圧に応じてほぼ直線的に変化する。 しかしながら、大信号状態下では、出力接続点(14)に接続されたレール−レール大信号出力ブースト段は、負荷によって要求される電流を必要に応じて提供するために、第1または第2の電源レールの近くに出力接続点をドライブするようになされている。 大信号出力ブースト段は、小信号状態ではオフであるが、大信号状態の下では急激にオンになり、最大電荷が負荷に引き渡される。

PROBLEM TO BE SOLVED: To decrease the influence when a noise is superimposed on the power source of a preamplifier inside a read amplifier for driving a magneto-resistance effect element head. SOLUTION: This single end type high frequency amplifier is composed of a transistor (21), differential input amplifier (40) and loop amplifier (30). In this case, a transistor (23) having the same output load as the output load of the transistor (21) on the preceding stage connected to the input side terminal of the differential input amplifier (40) is connected to a reference side terminal and the differential voltage between the reference side terminal and input side terminal of the differential input amplifier is fed back through the loop amplifier (30) to the single end type transistor so that the noise guided to the power source can be canceled.

PURPOSE: To unnecessitate any coupled transformers between stages in an amplifier for an on-vehicle receiver. CONSTITUTION: Amplifying stages 2 and 1 are erectly connected with polar bridges 10-12 in a static state, and cascade-connected in a dynamic state. The output of a first stage 2 is connected through an impedance matching reactance with the input of the next stage 1. A gain is controlled by pouring/extracting currents between an output terminal S of the amplifier and a pouring/extracting terminal A on the input of the first stage 2. | ||||||
