Classification: CPC H  G | IPC G  H

Claim 16:
17. A method comprising:
generating an electrical current based on received illumination using a photodetector;
integrating the electrical current to generate an integrator voltage using an integration capacitor;
controlling a transistor switch coupled in series between the photodetector and the integration capacitor using an amplifier;
sensing a high-energy event affecting the photodetector;
in response to sensing the high-energy event, closing a switchable clamp coupled across inputs of the amplifier; and
limiting a skew of a signal generated by the amplifier for a gate of the transistor switch using a de-bias protection diode coupled to an output of the amplifier and to the gate of the transistor switch.
