Title:
COLOR GAIN CONTROLLABLE CIRCUIT
Document Type and Number:
WIPO Patent Application WO/1982/001110
Kind Code:
A1
Abstract:
A color gain controllable circuit used for a color-television receiver or the like, which comprises a manually gain-controllable circuit and an automatically gain-controllable circuit cascode-connected between a source and reference potential. The automatically gain-controllable circuit is connected before the manually gain-controllable circuit. By cascode-connecting the manually-and automatically- gain-controllable circuits, both of the circuits can be made in one unit to greatly simplify the circuit-construction of the color gain controllable circuit and make it possible to integrate a color amplifying section.
