摘要： The present invention relates to a technology capable of compensating for a frequency error in a quadrature relaxation oscillator. The quadrature relaxation oscillator generates a signal at a desired frequency by using a resistor and a capacitor which are less sensitive to a PVT (Process, Voltage, Temperature) variation, generates a signal at a desired frequency by compensating for an error from design, which is caused by a mismatch between circuits due to a characteristic of a semiconductor process, through a feedback lop, and removes noise.
