Wideband low noise CMOS transimpedance amplifierfor gigaHertz operation

Abstract

A novel low noise CMOS common gate transimpedance amplifier is presented. Simulated performances gives a 1.2 GHz bandwidth, 1.6 kΩ transimpedance gain, and very low input referred current noise. Results are comparable to those of a recent common base BiCMOS transimpedance amplifier.
