A 1-V 1.25-GS/S 8-Bit Self-Calibrated Flash ADC in 90-nm Digital CMOS

摘要

We present an 8-bit 1.25-GS/s flash analog-to-digital converter (ADC) in 90-nm digital CMOS with wide analog input bandwidth and low power dissipation. The ADC employs two key techniques: a self-biased track-and-hold amplifier which enhances the AD
