摘要: A multiplying digital to analog converter using ladder networks and binary weighted load compensation allow integration video frequency operation. In one form, the circuit is configured from field effect transistors which incorporate by virtue of their structural operational characteristics both switching resistive functions R-2R networks. The used convert format words representing intensity color (red, green blue) into red, blue display drive signals. According that configuration, output word serves as reference for three converters. Loading effects attributable differences in bit content are offset a switched responsive word. also connected converter. This configuration provides an implementation (hue saturation) form can be held constant while selectively varied.
