Popis:	A two channel time-interleaved 14-bit 500MS/s charge domain pipelined ADC with mix-signal for-ground mismatch calibration method based on binary search is proposed. The offset and gain error mismatch between the two channels are calibrated in the mix-signal for-ground calibration. The 14-bit 500MS/s charge domain pipelined ADC is designed and realized in a 1P6M 0.18$\mu$m CMOS process. Test results show the 14-bit 500MS/s ADC achieves the signal-to-noise ratio of 69.8 dBFS and the spurious free dynamic range of 82.3dB, with 72.1MHz input at 500MS/s, while consumes the power consumption of 365mW.
