Abstract

A bipolar current amplifier using modified Wilson current mirrors in a feedback configuration to avoid the effects of voltage modulation is presented. An output of 20-mA ppk has been obtained with only 1-percent harmonic distortion irrespective of load and with proportionally lower distortion at reduced output current.
