Abstract
A circuit and method for timing-tolerant optical pulse energy electrical conversion receives a current pulse stream converted from an input optical pulse stream (which may be periodic or nonperiodic), converts the current pulse stream to an electrical waveform of voltage pulses and detects each voltage pulse, e.g., by its leading edge. The conversion circuit may include a divider circuit for receiving the electrical waveform, dividing the waveform into a multi-channel output of divided electrical waveforms, and sequential logic circuits for adjusting a width window of each voltage pulse according to an adjustable delay.
