Abstract
PURPOSE: To reduce the waveform distortion due to clipping and to avoid the variance in FM allocation, by constituting a feedback loop so that the difference of temperature characteristic between elements in a monolithic IC and peripheral components can not be affected.
CONSTITUTION: Transistors (TRs) Q7, Q8 constitute a differential amplifier, a signal amplified at this differential amplifier is picked up at the collector of the TRQ8 and applied to a clip circuit 8 via a buffer TRQ9. A signal outputted from a terminal (c) is given to a terminal (j) of a monolithic IC27 via a buffer circuit 35 consisting of a TRQ6 and resistor R15, level shift circuit 36 consisting of a Zener diode D2, capacitor C6, and resistor R16, and R17, and the terminal (j) is connected to the base of the TRQ8 constituting a differential amplifier to form a negative feedback loop.
