Abstract

This paper describes a differential amplifier which is based on the discrete/op-amp combo design, the noise performance test method and the test results are also given. Experiments shows that an ultra-low noise amplifier are achieved, the Bipolar input amplifier's input equivalent noise density is less than 2nv/rt-Hz, the BIFET input amplifier's input equivalent noise density is less than 5nv/rt-Hz. The combo design scheme presents high low-noise performance which matches traditional complex discrete component design but exceeds it with much more simplicity and feasiblility.
