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

    摘要: A gallium arsenide NAND gate (100) is connected between a power source (V DD ) and a ground potential. The gate (100) is comprised of a load transistor (20) of a normally-on type field effect transistor having an output terminal (C) and a drain connected to the power source (V DD ), a first driver transistor (22) of a normally-off type field effect transistor having a gate electrode as a first input terminal (IN,) and a source-to-drain current path series-connected to that of the load transistor (20), and a second driver transistor (24) of two normally-off type field effect transistors (24A, 248) having a common gate electrode for a second input terminal (IN 2 ) and source-to-drain current paths series-connected between the power source (V po ) and the ground potential through the series-connected first driver transistor (22) and load transitor (20). The normally-off type field effect transistors (24A, 24B) are parallel-connected to each other so as to equally constitute a single driver transistor as the second driver transistor (24).
