Charge-compensated correlated level shifting for single-stage opamps

High-precision analogue circuits suffer from the finite gain and non-linearity of operational amplifiers (opamps). Correlated level shifting is one efficient technique that provides gain and swing enhancement for switched-capacitor circuits. Charge-compensated correlated level shifting is proposed,...

Zusammenfassung:	High-precision analogue circuits suffer from the finite gain and non-linearity of operational amplifiers (opamps). Correlated level shifting is one efficient technique that provides gain and swing enhancement for switched-capacitor circuits. Charge-compensated correlated level shifting is proposed, a modification for the correlated level shifting technique, that improves the efficiency of gain enhancement for single-stage opamps.
