Filed: 1985-04-19
Abstract: PURPOSE:To vary a bias point and to suppress the fluctuation of a synchronous peak level by permitting the fluctuation of a direct current voltage owing to the fluctuation of synchronous peak level to make a feedback to a bias circuit in the input part of a clamping circuit. CONSTITUTION:As regards image signals Vin inputted into clamping circuit, synchronous peal levels VSYNC are extracted by closing a switch 10 through clamping pulses which occur from a clamping occurrence circuit 13 to positions of synchronous signals. Whenever the extracted synchronous peak levels allow its switch 10 to keep on a state of turning on, its ON period is maintained by a capacitor 11 to be used for holding. A difference between the extracted synchronous peak level VSYNC and reference level Vr is amplified by a differential amplifier 12 and supplied a transistor 7 consisting of buffer circuit 4. Supposing the synchronous peak levels VSYNC become higher, base potentials VB of the transistor 7 will be higher but collector potentials VC will be lower. Likewise, the more the synchronous peak levels VSYNC become low, the more the collector potentials VC become high.
