Abstract

PURPOSE:To improve the voltage gain between the input and the output practically, by shifting the level of the output signal in the drain electrode of the first GaAsFET by a required quantity and by applying this signal to the gate electrode of the second GaAsFET. CONSTITUTION:When the first GaAsFET starts escaping from the pinch-off state, the voltage of each part is changed. A current is flowed to the first FET, and drain voltage VO1 starts falling slightly, and gate voltage VG2 of the second GaAsFET starts falling. Since the first FET starts operating as a source follower circuit, source voltage VS rises by DELTAV according to rise of gate voltage VG1. Source voltage VS of the second FET falls by DELTAV' also. The current flowed to the first FET is increased to cause drain voltage VD1 to fall from the position of arrow 403 slightly. Voltage VG2 of the second FET falls from the position of arrow 404 slightly also, and voltage VS falls by DELTAV''. By repeating this course, respective voltage values reach a stable point.
