Design of a Three-Stage High-Bandwidth CMOS Transimpedance Amplifier

This report describes the development of a transimpedance amplifier that takes current as input and gives voltage as output. The amplifier consists of three CMOS amplifier stages in a fed-back configuration, achieving a transimpedance gain over 3 kΩ and a 3-dB bandwidth greater than 2.8 GHz. The amplifier operates with a 1.5 V supply voltage and a power budget of 30 mW.

Transimpedance amplifier with differential photodiode current sensing

This paper presents a balanced receiver structure suitable for wireless infrared data communications. The receiver provides a fixed photodiode bias voltage with the use of a regulated cascode input stage. Together with an active feedback loop used to eliminate dc photocurrents, the receiver implements ac coupling without the need for matching capacitors. Differential sensing of the photodiode c...
