Abstract
A switched capacitor circuit is described that uses two switchable operational amplifiers that operate in parallel and in alternate clock phases. In a preferred embodiment of the invention, the two operational amplifiers may be implemented by a single two-stage operational amplifier having a common input stage and two switchable output pairs. The novel switched capacitor circuit may be used in any application that uses a conventional switched capacitor circuit, such as an integrator and a filter means.
