This paper hearsay on various design approach of transimpedance amplifier (TIA) that improves the performance along various parameters such as gain, noise, speed and bandwidth. Transimpedance amplifier design overcomes the drawbacks of high impedance amplifier design. Gain boost up can be done by using PMOS current source at the input stage. Capacitive coupling and cross coupled current conveyor stage trim down input noise and get better the speed of transimpedance amplifier.
