Abstract
An optical pulse to voltage signal converter may include a photodetector, a front end-circuit, and a signal processor. The front-end circuit may include a tunable loading network configured to convert a stream of current pulses from the photodetector into a stream of input voltage signals, at least one tunable voltage source configured to generate at least one stream of signals with at least one select voltage, and at least one amplifier coupled to the at least one tunable voltage source. The at least one amplifier may be configured to compare the stream of input voltage signals and the at least one stream of signals with the at least one select voltage to generate at least one stream of output voltage signals with a select duty-cycle phase and duty-cycle resolution. The amplifier may be further configured to output the at least one stream of output voltage signals to the signal processor.
