Title: Oscillator
Inventor: UCHIDA HIDEYUKI
IPC: H03B5/12
Filed: 1990-08-31
Abstract: PURPOSE:To remove the fall of C/N and S/N, and to improve the yield of an oscillator by interposing a tank circuit between the input side and the output side of an amplification element. and interposing an impedance element between the output side and the tank circuit. CONSTITUTION:The collector of a transistor TR is connected to the tank circuit RC through the impedance element Z. Since a collector current IC flows to the collector of the transistor TR through the impedance element Z, the collector current IC is limited by the impedance element Z, and a charging current to flow to the tank circuit RC is reduced, and voltage generated between across a capacitor C2 is reduced. The amplitude of a base current IB is suppressed to the value to make the shallow area of the non-linear area P of the base current and a collector current characteristic curve P. Accordingly, the base current IB of the transistor TR is stabilized at the suppressed amplitude, and the oscillating operation of the tank circuit RC is stabilized. Thus, the yield of the oscillator can be raised inexpensively through a simple circuit, and the C/N (carrier-to-noise ratio) and the S/N (signal-to-noise ratio) can be improved.
