Popis: This paper presents a 12-bit 200-MS/s dual channel pipeline analog-to-digital converter (ADC). The ADC is featured with a digital timing correction for reducing a sampling skew and the capacitor swapping for suppressing nonlinearities at the first stage in the pipelined ADC. The prototype ADC occupies 0.8x1.4mm^2 in a 65-nm CMOS technology. The differential nonlinearity is less than 1.0 least significant bit with a 200MHz sampling frequency. With a sampling frequency of a 200-MS/s and an input of a 2.4MHz, the ADC, respectively, achieves a signal to noise-and-distortion ratio and a spurious-free dynamic range of 61.49dB-70.71dB while consuming of 112mW at a supply voltage of 1.1V.
