Sub-picosecond-jitter clock generation for interleaved ADC with Delay-Locked-Loop in 28nm CMOS
Öffentlich DepositedThis paper presents a Delay-Locked-Loop (DLL) using a low-jitter design technique to generate sub-picosecond-jitter interleaved ADC sampling clock phases. To mitigate the effects of jitter accumulation, a low jitter delay line with digital control circuit is proposed. After 10 delay stages, the proposed DLL output can achieve <;0.1psrms jitter clock. The DLL can operate with input clock frequency from 2GHz to 10GHz, enabling interleaved ADC sampling with a low-jitter sample clock over a 20GHz to 100GHz frequency range.
