Abstract
A comparator-based switched-capacitor (CBSC) integrator is presented. In contrast to an opamp-based switched-capacitor (OBSC) circuit, a comparator-based switched-capacitor circuit needs an extra circuit to control the charge flow in the charge transfer phase. A new charge control circuit is proposed to control the charge transfer phase of a CBSC integrator. In comparison to the existing charge control scheme, the proposed charge control scheme makes the output settling faster.
