A 16-bit,±10-V Input Range SAR ADC with a 5-V Supply Voltage and Mixed-Signal Nonlinearity Calibration
文献摘要：
This paper presents a high-precision,suc-cessive approximation register(SAR)analog-to-digital converter(ADC)with resistive analog front-end for low-voltage and wide input range applications.To suppress the serious nonlinearity brought by the voltage coeffi-cients of analog front-end without deteriorating differen-tial nonlinearity performance,a mixed-signal calibration scheme based on piecewise-linear method with calibration digital-to-analog converter is proposed.A compensation current is designed to sink or source from the reference to keep it independent of input signal,which greatly im-proves the linearity performance.Fabricated in a 0.5-μm CMOS process,the proposed ADC achieves 88-dB signal-to-noise-and-distortion ratio and 103-dB spurious free dy-namic range with 5-V supply voltage and 2.5-V reference voltage,and the total power consumption is 37.5 mW.
