AMPLIFIER STAGE Russian patent published in 1997 - IPC

FIELD: microelectronics, applicable for amplification of signals. SUBSTANCE: amplifier stage uses the first and second pairs of field-effect transistors, the sources of the first transistors are connected to the common bus, the sources of the second transistors of the pairs are connected to the power supply bus, the drains of the first transistors of the pairs are connected to the sources of the second transistors of the pairs, the gate of the second transistor of the first pair is connected to the source of the second transistor of the second pair, and the gate of the second transistor of the second pair is connected to the source of the second transistor of the first pair, voltage follower with a shift of levels and a voltage divider, whose output is connected to the gate of the first transistor of the second pair, and the input - to the output of the voltage follower with a shift of levels, whose input is connected to the gate of the second transistor of the second pair. EFFECT: improved design. 4 dwg
