In this digital calibration technique, there is no extra replica CP needed. In addition, it can calibrate the CP under different control voltages on the loop filter to be immune to the channel-length ...

Abstract: A 6-bit 2.5-GS/s 8× dynamic interpolating flash analog-to-digital converter (ADC) with an offset calibration technique for interpolated voltage-to-time converters (VTCs) is presented for ...
