Online Simulation of a Transimpedance Amplifier Circuit
This fast photodiode transimpedance amplifier is based on a high- speed JFET- input op amp OPA657.
This op amp is compensated for a minimum closed- loop gain of 7V/V, but the capacitance of the photodiode plus the op amp input capacitance together with the feedback resistor R1 provides a noise gain at high frequency that allows stable operation.
Compensation capacitor C1 optimizes the amplifier bandwidth / gain peaking tradeoff.
Achieving this level of performance requires very careful layout and the circuit must be shielded to prevent noise pickup.
