Title: Semiconductor integrated circuit
Inventor: SATO FUMIHIKO
IPC: H03F3/34
Filed: 1990-08-23
Abstract: PURPOSE:To generate an output including no offset output by providing a variance detecting circuit part, which detects the variance of the input bias given from an oscillating transistor TR to an input bias circuit part, and an adjusting circuit part which controls a reference bias circuit part based on the detected variance to adjust the reference bias in accordance with this variance. CONSTITUTION:When the external resistance of an oscillator is adjusted to change the oscillation frequency, the base current of an oscillating TR 4 is varied by this adjustment of the external resistance. When a variance detecting circuit part 5 detects the variance of the base current of the oscillating TR 4 based on the adjustment of the external resistance, an adjusting circuit part 6 controls a reference bias circuit part 2 to adjust the reference bias voltage so that this voltage coincides with the input bias voltage. Thus, the reference bias voltage always follows up the input bias voltage to be equal to the input bias voltage regardless of the variance of the input bias voltage at each time of changing the oscillation frequency, and therefore, the oscillation output outputted from a differential amplifying circuit 1 does not include the offset output.
