Abstract
In a configuration wherein an output signal from a differential oscillator is input into a differential buffer amplifier, an operating current for the differential oscillator including a resonator, which has a node at the midpoint of an inductor, and a pair of field-effect transistors for oscillation and an operating current for the differential buffer amplifier including a pair of bipolar transistors for amplification are made common. In order to obtain the common operating current, the current from the pair of bipolar transistors for amplification is fed from the midpoint of the inductor into the pair of field-effect transistors for oscillation.
