THE ANALYSIS OF TRANSMITTING FEATURE OF PUSH-PULL SYMMETRIC DIRECT CURRENT AMPLIFIER

Abstract

The paper considers the principles of the push-pull symmetric current amplifiers building. The indicated method, despite the traditional asymmetric structure, stipulates fort the push-pull input cascade in the form of self-complete circuit with the common base, two symmetric intermediate cascades and push-pull symmetric output cascade. There had been deducted the equations for current transmission rate into separate amplifier’s channels of push-pull symmetric constant current amplifiers, total current transmission rate for low signal zone and high signal zone, nonlinearity of transmission rate. There had been given the simplified circuit of symmetric structure constant current amplifier. There had been proved that the circuits of push-pull symmetric constant current amplifiers have smaller error of linearity transmission rate.
