摘要：

The EF-AJC is a mixed signal circuit operating with GHz sawtooth waveforms and feedback time constants of a few milliseconds. Jitter has to be modeled to sub-picosecond accuracy. Conventional time-step simulation is impossible in reasonable time. The paper addresses the validity of the 'indirect' simulation methods that have to be used. The 'simulations' are compared with 500MHz results from a Fujitsu Mcro-Electronics test chip. This 90nm chip suppresses jitter by 8 times. The estimated residual jitter is less than an estimated 2 to 5ps.
