PCT No. PCT/JP86/00639 Sec. 371 Date Oct. 9, 1987 Sec. 102(e) Date Oct. 9, 1987 PCT Filed Dec. 17, 1986 PCT Pub. No. WO87/04027 PCT Pub. Date Jul. 2, 1987.A slice amplifier using field effect transistors (FET's) is provided which 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. |
