Abstract
A differential input is applied to four bridge-connected field effect transistors. The bridge drives a differential common base transistor stage. The output can be either differential or single ended as desired taken from the transistor collectors. The circuit provides good common mode rejection and good differential response to signals over a common mode range that exceeds the voltage of the power supply.
