Abstract :
A direct-charge-transfer adder is described for wideband low-power delta-sigma ADCs. Its operation and design are discussed in detail. Its application to noise-coupled delta-sigma ADCs is also described. To verify the proposed design methodology, a 2nd order noise-coupled delta-sigma ADC using direct-charge-transfer adder has been designed and simulated.
