Photodiode digitizer with fast gain switching










Image Number 4 for United States Patent #7365665.

An optical receiver and method of operating therfor. A photodiode converts a received optical signal to an electrical signal, which is provided to both high gain and low gain signal paths. First analog-to-digital converter ADC) circuitry is coupled to convert a high gain output signal into a first plurality of digital signals, while second ADC circuitry converts a low gain output signal into a second plurality of digital signals. A control unit is configured to monitor the amplitude of at least one of the low gain and high gain output signals. If the amplitude of the monitored signal falls below a predetermined threshold, the control unit is configured to select data provided by the first ADC circuitry. Otherwise, data provided by the second ADC circuitry is selected.
