Title:
DIFFERENTIAL OSCILLATION CIRCUIT
Document Type and Number:
Japanese Patent JP2005198084
Kind Code:
A
Abstract:
To provide a differential oscillation circuit which is capable of causing a differential oscillator and a differential buffer amplifier to function with a common operating current.
A resonator 14 having a middle point of an inductor 16 as a nodal point is provided, and a differential oscillator 12 to which the operating current is supplied from the middle point of the inductor 16 and a differential buffer amplifier 11 having a pair of bipolar transistors 24 and 25 operated with the operating current as a tail current are provided, and they are so configured that an output signal of the differential oscillator 12 is inputted to the differential buffer amplifier 11.
