DC Photocurrent Rejection of High Transimpedance Gain Preamplifier in Infrared Wireless Optical Receiver

摘要：

A high gain transimpedance preamplifier in the infrared wireless optical receiver is presented.Employing an active inductor as the active cancellation scheme,a novel de photocurrent rejection technique of a transimpedance amplifier (TIA)is designed to eliminate dc photocurrent generated by ambient light.Implemented in Chartered 0.35μm CMOS technology,the preamplifier provides a transimpedance gain of 120dBΩ and the current sensitivity of 500pA,and achieves to reject the de photocurrent with the range of 0μA to 20μA. Operating under a 3.3V supply,the power dissipation is 0.6mW.
