Title:
VOLTAGE GENERATING CIRCUIT, OSCILLATOR CIRCUIT, AND INTEGRATED CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2024/112045
Kind Code:
A1
Abstract:
The present invention relates to a voltage generating circuit, an oscillator, and an integrated circuit, the oscillator comprising: a first circuit for outputting a reference voltage; a second circuit that is connected to the first circuit and comprises a resistor of which the resistance value changes in response to changes in temperature; and a third circuit for generating a signal at a frequency corresponding to the reference voltage outputted from the first circuit, wherein the value of the reference voltage outputted from the first circuit is adjusted by the second circuit in response to changes in temperature. According to an embodiment, the oscillator may provide a stable oscillation frequency by reverse-compensating the reference signal, inputted to a core oscillator circuit, for the changes in temperature.
