Підсилювач постійного струму

Abstract

The invention proposes a dc amplifier, wherein it is reached independence a through collector current passing through output stages of the dc amplifier from a through collector current passing through input stages of the dc amplifier. “A current suspension” reacts to changes of an input signal and provides a direct through current passing through collectors of output stages’ transistors. To better characteristics of the dc amplifier a high-precision current mirror is used.
