Abstract

In this paper, the Correlated Jitter Sampling (CJS) technique, which alleviates the jitter induced error from the time reference in pipelined Time-to-Digital Converter (TDC), is proposed. The auxiliary pipelined TDC is employed to remove the jitter induced error of the main pipelined TDC in the CJS technique. A 12b pipelined TDC adopting the CJS technique in the 1st time quantization stage is simulated to validate the proposed technique. Simulation results show that the TDC can achieve a flat SNDR performance of 70dB regardless of the jitter from time reference up to 25% jitter of 1TLSB in reference clock, which is the maximum error allowed within a designed redundancy range of the pipelined TDC.
