Abstract
PURPOSE: To substantially remove a phase shifting operation generated by an amplifier, by setting an operating point almost equally to an input differential amplification stage of a double balanced cascode amplifier, and amplifying a synchronizing carrier wave through a differential amplifier constituted of the same coupling method.
CONSTITUTION: Input signal voltage E1 is supplied to multipliers 21, 22 through amplifiers 11, 12. An output signal of the multiplier 22 constituting an APC detector controls a voltage control oscillator 40 through a low-pass filter 30, its output signal is selected as a synchronizing carrier wave to the same ground form as the amplifier 12, and also is supplied to the multiplier 22 through an amplifier 52 to which its operating point has been set so as to be almost equal, as well. To the multiplier 21 constituting a video detector, the output signal of the oscillator 40 is supplied through a phase shifter 60 and an amplifier 51, and 2 amplifiers 11, 51 offset a phase shifting operation generated due to arrangement of the amplifiers so that a relative phase shift difference between 2 input signals of the multiplier 21 becomes "0" or π (rad).
