Abstract :
Simulation of the dynamic performance of a flash analog-to-digital (A/D) converter is complicated due to the presence of many systematic and random dynamic errors. A simulation methodology is proposed where all of the dynamic errors in the converter are lumped into an effective timing uncertainty of the sampling clock. The effective timing uncertainty is a function of the signal dynamics, and completely characterizes the dynamic behavior of the converter. The signal-to-noise plus distortion ratio (SNDR) of an 8-bit bipolar converter was simulated using this methodology. The simulation results are presented
