Abstract
A signal averaging circuit includes a plurality of switched weighted current sources to generate a total amount of charge. The total amount of charge is representative of a weighted sum of a plurality of input signal samples during an active period of a read enable signal. A timing control signal generator is coupled to receive an input signal and the read enable signal and sequentially switch the plurality of switched weighted current sources to adjust the total amount of charge in response to the input signal during the active period of the read enable signal. A storage circuit is coupled to the plurality of switched weighted current sources to convert the total amount of charge into a voltage representative of an output signal.
