We consider a circuit design method to increase a slew rate increase and transient process setting time decrease in buffer amplifiers (BAs), intended for operation in analog interfaces of physical values sensors and automatic devices at low temperatures. Differentiating transient correction circuits are introduced into the classical circuits of the BAs on complementary field-effect transistors (CJFETs) to improve these dynamic parameters. We investigated two buffer amplifier’s topologies: single-ended and balanced ones. The article shows the practical use of the proposed BA in the output and input stages of the high-speed operational amplifiers.
