Abstract
A 250 MS/s cascaded two-stage 5-bit pipelined SAR ADC in 90nm CMOS was designed and validated. Elimination of passive components leads to an improvement in power utilization, improvement in speed and at the same time is not limited by process variations. The SAR ADC design was validated as a Matlab/Simulink macro model and verified in 90nm CMOS through Agilent ADS. Successive approximation for each stage is achieved through a binary search in a round robin mode that reduces the approximation time. DNL was observed to be 0.7 LSB.
