A promising optoelectronic clock solution for time-interleaved ADC

Abstract

Abstract A promising optoelectronic clock solution with low jitter, high bandwidth and accurate delay for a TIADC is proposed by exploiting optical pulses and tunable optical delay lines. It is feasible to construct the optoelectronic clock system with optical pulse source, dispersive medium, tunable delay line in optical domain and conditioning circuits in electronic domain while photodiodes as the bridge. The testing result of the designed conditioning circuit shows that using electronic method to adjust the signal will induce jitter degradation of the optoelectronic clock system.
