This paper presents a 10-bit 1-GS/s four-channel time-interleaved (TI) successive approximation register (SAR) analog-to-digital converter (ADC). To suppress the time skew, the full rate master clock-based sampling technique is adopted. The effect of sampling switch mismatches on time skew is addres...
