Abstract :
The method of using small-signal model to analyze jitter of the clock driver caused by thermal noise is presented. Multi-stage quasi-infinite load differential amplifier structure to effectively achieve low clock jitter is proposed. With transient noise simulation, jitter in the clock driver can be calculated. Through testing the SNR of ADC, The jitter of the designed clock driver in this paper is below 260 fs so that it can be used in the high performance ADC.
