Design of CMOS based Transimpedance Amplifier for Bandwidth Enhancement with Large Gain

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.

High bandwidth transimpedance amplifier design using active transmission lines

A transimpedance amplifier (TIA) is designed based on the first order wave equation. The feedback resistance is set as the ohJective function for transimpedance. The main feedback amplifier provides transimpedance and a wide band compensation amplifier determines the characteristics of overall TIA. The stability of lhe T lA is not affected due to the open loop nature of compensation. Simulation...

High-gain differential CMOS transimpedance amplifier with on-chip buried double junction photodiode

Introduction: The transimpedance amplifier (TIA) is widely used in optical receiver circuits. The majority of CMOS TIA designs reported in the literature are intended for high speed digital signal reception. The TIA reported in this Letter is optimised for low noise analogue optical signal detection, in a situation where a weak modulated optical signal is superimposed on a large DC background. ...

A High - Swing 2 V CMOS Operational Amplifier with Gain Enhancement using a Replica Amplifier

This open-loop gain enhancement circuit in 1.2pm CMOS does not require cascode or long-channel transistors, thus maximizing output swing and input common-mode range [1,21. Since gain enhancement is achieved not by increasing output resistance, but by matching main and replica amplifiers, high effective open-loop gain is maintained even with resistive loads. This circuit can be used with any tra...
