High Sensitivity Transimpedance Photodiode Amplifier

Description

SPICE simulation of a transimpedance amplifier that amplifies an input current signal to a voltage signal. In this circuit the photodiode is represented by the current source with its shunt capacitance. The JFET op amp provides low input offset voltage and drift, low input bias current and low noise. The high feedback resistor gives high gain and low noise but reduces the bandwidth.
