Abstract
Disclosed is a D/A converter including a DC processing circuit, an analog switching device, a bootstrap circuit, and a third order low-pass filter. The boots trap circuit substantially reduces loading created by the low-pass filter circuit and acting on the switching device. Cross-over discontinuities in the continuous analog signal are reduced by interposing between each two successive pulses a cross-over correction pulse having opposite polarity and a predetermined fixed pulse-width. The D/A converter provides fast and accurate response over a long period of time.
