摘要：
A digitally controlled oscillator includes a ring oscillator, a parallel resistor bank connected to a first terminal of the ring oscillator and having a resistance that varies according to a digital code, and a serial resistor bank connected to a second terminal of the ring oscillator and having a resistance that varies according to the digital code. A frequency of the ring oscillator linearly varies with a variation in the resistance of the parallel resistor bank and the resistance of the serial resistor bank according to the digital code.
