Abstract :
Three different digitally-assisted analog designs are presented to demonstrate the powerful way to solve the analog design deficiencies in the submicron CMOS technology. A 200 MS/s 12-bit pipeline ADC is using the split-capacitor correlation method to solve the linear and nonlinear problems. A 1 GS/s 14-bit current-steering DAC is using the programmable sub-DAC to continuously trimming the current mismatches. A 25 MS/s 16-bit ΣΔ ADC is using the adaptive way to correct the leakage noise and DAC nonlinearity.
