Abstract :
Passive charge redistribution can be used to perform partial settling in a SC circuit. Two charge redistribution techniques employing a pulling capacitor and current pumping are proposed for settling performance enhancement. Possible implementations in a delayed integrator and a switched-capacitor residue circuit are discussed. Finally, an extremely simple pre-charge method is discussed to minimize the non-linear settling error in a SC residue amplifier.
