Abstract
A switched capacitor filter for applying a filter processing including an integration processing to input analog signals of plural channels on a time shared basis includes an integration sections for sequentially implementing the integration processing for the respective channels on a time shared basis, integrated value storage sections for storing integrated value signals representing results of the integration processing for the respective channels, switches for causing, each time the integration processing for the respective channels is interrupted, an integrated value signal representing result of the integration processing for the particular channel at the time of interruption to be stored in the integrated value storage sections and initializing the result of the integration processing by the integration section and, each time the integration processing for the respective channels is implemented, supplying the integrated value signal for the particular channel from the integrated value storage sections to the integration section and supplying also an analog signal to be processed in the integration processing to the integration section.
