A SLICE AMPLIFIER USING FET'S

摘要

A slice amplifier using field effect transistors (FET's) is suitable for achieving a correct discrimination of logics ''0'' and ''1'' of an input signal (Sin) at very high speed by reshaping the input signal (Sin) into rectangular shaped pulses (Sout). The top and bottom of each pulse are determined to predetermined constant levels by using a first FET (T1) and a second FET (T2) with the aid of a first monitor and control unit (41) and second monitor and control unit (42). The first and second monitor and control units (41, 42) monitor the drain voltages of the first and second FET's (T1, T2) and control the gate-source voltages thereof, respectively, so as to realize the predetermined constant levels.
