Abstract
This paper presents a clock generator circuit for a high speed analog-to-digital converter (ADC). A time interleaved ADC requires an accurate clocking for the converter fingers. The target ADC has 12 interleaved fingers each running at speed of 166 MS/s which corresponds to equivalent sampling frequency of 2 GS/s. A delay-locked loop (DLL) based clock generator has been proposed to provide multiple clock signals for the converter. The DLL clock generator has been implemented with a 0.35 /spl mu/m SiGe BiCMOS process (only MOS-transistor were used in DLL) by Austria Micro Systems and it occupies 0.6 mm/sup 2/ silicon area. The measured jitter of the DLL is around 1 ps and the delay between phases can be adjusted at 1 ps accuracy.
