Description
SPICE simulation of laser energy meter. The IVC102 is a precision integrating amplifier with FET op amp, integrating capacitors, and low leakage FET switches, capable of integrating the output of a very fast detector. It integrates low-level input current for a user-determined period, storing the resulting voltage on the integrating capacitor.The output voltage can be held for accurate measurement. The IVC102 provides a precision, lower noise alternative to conventional transimpedance op amp circuits that require a very high value feedback resistor.
