Abstract
There is provided a resistor-capacitor (RC) oscillator circuit insensitive to process, voltage, and temperature variances. The RC oscillator circuit includes a delay unit, a resistor unit, a capacitor, a resistor, and a first controller. The delay unit delays and outputs a signal received through an input terminal. The resistor unit is connected between an input terminal of the delay unit and a first node. The capacitor is connected between an output terminal of the delay unit and the first node. The resistor is connected between the input terminal of the delay unit and an output node. The first controller is connected between the output terminal of the delay unit and the output node, wherein a frequency signal is output through the output node.
