| Abstract: | A 3.3 V,9-bit,50 MS/s pipeline analog-to-digital converter(ADC) is presented,in which an 8-stage(1.5-bit /stage) pipelining architecture is adopted.Each stage resolved two bits and the resulting 16 bits are combined with digital correction to yield 9 bits at the output of the ADC.Simulation results show that the ADC achieved a signal-to-noise ratio of 54.624 dB,maximum differential nonlinearity of 0.6 LSB,maximum integral nonlinearity of 1 LSB,and an ENOB of 8.712 bits with only 82 mW of power. |
