Open full text 1 citations

Abstract

A high performance low noise common gate CMOS cascoded transimpedance amplifier designed and simulated in a 0.35 micrometers CMOS technology is presented in this paper. This novel transimpedance amplifier design provides a transimpedance gain of 1k(Omega) with a -3db bandwidth of 2.49GHz, with the input and output noise current spectral density of 7.08pA/(root)Hz and 7.09nV/(root)Hz respectively. With the rapidly emerging optical data-communication technology, this amplifier design is thus well-suited for optical transceiver applications such as the OC-48 standard.
