Abstract
An oscillation signal generation circuit includes an oscillator and a calibration circuit. The oscillator includes a reference signal source circuit that has a reference signal source outputting a reference signal and converts the output reference signal into a control voltage, a filter that includes a variable resistance and a capacitance and removes noise in the control voltage, a transistor that converts the control voltage which has passed through the filter into a control current and outputs the control current, a core circuit that is driven by the control current and generates an output signal, and an output terminal that outputs the generated output signal. The calibration circuit is connected to the output terminal of the oscillator, detects whether or not the generated output signal is oscillating, and adjusts the current value of the control current by controlling the resistance value of the variable resistance in accordance with the detection result.
