Abstract
A monolithic integrated circuit which performs the subcarrier regeneration task in a color television receiver is described. Differential amplifier configurations are used in a novel circuit concept which involves time-sharing and current switching techniques. The result is a realization of the design objectives with a relatively simple structure. The burst gate, phase detector and voltage controlled oscillator functions called for by the classical APC loop are provided. In addition, an in-phase detector for color killing and chroma AGC is included, as well as a novel DC controlled hue adjustment.Keywords
