Abstract
Digital-to-analog conversion circuitry 100 is shown including a path for processing data in a 1-bit format. First portion of an analog finite impulse response filter 300 includes pre-selected number of delay elements 301 for receiving stream of data in the 1-bit format and outputting a plurality of signals in response. A switched capacitor digital-to-analog converter 106 forms a second portion of the finite impulse response filter 301 and has a plurality of elements each receiving one of the plurality of signals as selected to effectuate a set of filter coefficients, converter 106 summing the plurality of signals and outputting an analog data stream.
