Abstract :
A new comparator based MDAC is presented. This structure utilizes nonlinear charge transfer and time shifted CDS techniques to improve the performance of the comparator based MDAC. Simulation results show that the proposed MDAC can be utilized in pipeline ADCs to enhance accuracy and speed.
