Abstract
A digital to analog conversion system (10) includes a noise shaper (14) and a digital to analog converter (16). The digital to analog converter (16) includes a series of weighted taps (32, 102) with switched capacitor circuitries (42, 106, 108). The digital to analog converter (16) also includes an amplifier (36, 120) having an associated integrating capacitor (62, 122, 130). The switched capacitor circuitries (42, 106, 108) include capacitors (46) that are coupled in parallel to integrating capacitors (62, 122, 130) by common busses (34, 114, 115).
