Abstract

A CMOS wideband transimpedance amplifier with multiple‐resistive feedback loops is reported for first time. This amplifier was fabricated by the 0.35‐μm CMOS process. Multiple‐feedback technique was used to achieve terminal impedance matching and wide bandwidth. The experimental results showed that a transimpedance gain of 51.7 dBΩ and a 3‐dB bandwidth of 2.1 GHz were obtained. High input P~1dB~ of −5 dBm and input IP3 of 1 dBm were also measured. The high dynamic range and high linearity achieved were attributed to the multiple feedback technique used. © 2002 Wiley Periodicals, Inc.
