Abstract
An apparatus includes a Transimpedance Amplifier (TIA), an input interface and input masking circuitry. The TIA is configured to convert input current pulses into output voltage pulses. The input interface is configured to receive a control signal indicative of one or more time intervals. The input masking circuitry is configured to prevent the input current pulses from saturating the TIA during the one or more time intervals indicated by the control signal.
