Abstract

Great care must be taken when using SC techniques from a low supply voltage to ensure proper switch operation. A new approach to solve this problem (called switched opamp) has been recently proposed and it is based on turning on and off the opamps in SC circuits. In the Letter a modified version of the switched opamp approach is proposed. This results in a considerable increase of the signal swing for a given supply voltage and in a substantial reduction of the minimum supply voltage required for proper circuit operation.
