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.
