11-Bit 6.5MS/s SAR ADC for Wireless Applications
Keywords:
SAR ADC, triple level switching, non-binary, redundant algorithm.Abstract
A 1.3V, 11-bit, 6.5 MS/s Successive Approximation ADC is presented. The ADC operates with a differential peak to peak input of 1V. The ADC uses the common mode resetting triple level switching scheme, non-binary generalized redundant algorithm, a rail-to-rail latched comparator and a input bootstrapped sampling switch. The ADC was designed in 0.13um CMOS process. The simulation results of the ADC at an output data rate of 6.5 MS/s shows that it can achieve a signal-to-noise distortion ratio (SNDR) of 67.53 dB which corresponds to an Effective Number of Bits (ENOB) of 10.92. It also obtained a good linearity (DNL/INL) value of less than +-0.32LSB. The ADC consumes 414uW of power with a 1.3V supply resulting in a Figure of Merit (FOM) of 33 fJ/conversion-step.
