A control vibration generator for synchronous video detector having : the first, second input terminals which are able to be connected to outside elements; the first, second output terminals which aren't able to be connected to outside elements; the first differential amplifier of the first differential input/output mounted in inside of IC to display non-inverting differential mode voltage gain from said first, second input terminals and voltage gain from one of said output terminals; the first resistance potential divider connected to present the potential of said first output terminal of said first differential amplifier to said first input terminal of said first differential amplifier and positioned within said monolithic IC; the second resistance potential divider connected to present the potential of said second output terminal of said first differential amplifier to said second input terminal of said first differential amplifier and positioned within said monolithic IC; a winding having the first, second terminals connected to the first, second input terminals of said first differential amplifier; an inductor positioned in outside of said monolithic IC; and a capacitive means for being tuned against said inductor within resonance circuit; is disclosed. Thereby, it is possible to present regeneration feedback. |
