Abstract:
In this paper, the effect of capacitor non-linearity on the linearity of a pipelined ADC is analyzed. First, the effect of capacitor non-linearity on the characteristics of a 1.5-bit residue stage is discussed and its transfer function is calculated. Then, a closed-form formula for the SFDR of the entire ADC as a function of capacitor non-linearity coefficient is calculated. Behavioral simulations as well as transistor-level simulations of a 10-bit 10MS/s pipelined ADC in a 0.18 ¿m standard CMOS technology are presented to show the accuracy of proposed equations.
