Abstract
This paper presents a 6-bit, 1.2-GSample/s flash ADC with new proposed wideband track-and-hold amplifier (THA) fabricated in TSMC 0.13-mum CMOS technology. The wideband THA employs a front-end super source follower (SSF), which has a very low input capacitance of only 0.2-pf, to boost analog bandwidth without any on-chip passive inductor. Moreover, the flatness of the data bandwidth of ADC will improve. The SSF can also relax the power consumption of the voltage buffer in the THA.
