摘要：An amplifier arrangement comprising a first (T1) and a second (T2) field-effecttransistor of the same conductivity type and a driver circuit (Q1, Q2, Q3, T3, T4, T5, I) whichis responsive to a signal to be amplified at the input terminals (3, 4) to drive the
respective drain electrodes of the two field-effect transistors (T1, T2). A resistive element(R) is formed between the drain and the gate electrode of the first field-effect transistor(T1) and a capacitive element (C) is formed between the gate and the source electrode.Together with said elements (R, C) the first field-effect transistor (T1) constitutes areactance circuit having an inductive character, which is arranged in parallel with theparasitic gate-source capacitance of the second field-effect transistor (T2). This results inan improved step-function response and edge steepness of step-function signals on theoutput terminal (5), i.e., at the drain electrode of the second field-effect transistor (T2), incomparison with an amplifier arrangement without said reactance circuit. The circuit isvery suitable for integration in BICMOS technology.
