Abstract
The application discloses an RC oscillator circuit, relates to the technical field of integrated circuits, and aims at the problem that current RC oscillators cannot flexibly adjust the duty cycle of output square wave signals, and provides an RC oscillator circuit, which is characterized in that a first switch is connected with an adjustable capacitor at the output end of a square wave signal generating module; when the square wave signal output by the square wave signal generating module is at a certain level stage, the first switch is closed to connect the adjustable capacitor to the output end of the square wave signal generating module, and the connected adjustable capacitor can cause a delay when the square wave signal is flipped from the current level to another level; since the capacitance value of the adjustable capacitor is adjustable, the delay caused by the square wave signal when the square wave signal is flipped is adjustable, so that the effect that the duty cycle of the square wave signal can be freely adjusted is achieved.
