An 11b 1GS/s Time Interleaved ADC with Linearity Enhanced T/H

This paper presents a 1GS/s 11 bit 4 ×Time-Interleaved (TI) ADC employing the proposed Track-and-Hold (T/H) to enhance the sampling linearity and avoid timing skews. A dual auxiliary Source-Follower (SF) T/H provides signal double boosting to suppress the sampling distortion while maintaining good p
