Abstract

See full text

An RC oscillator is provided. The oscillator includes an RC selecting switch disposed in an input port of the oscillator, a resistor output port, a capacitor output port, at least a resistor switch with a first end connected to the RC selecting switch and a second end floatingly connected to the resistor output port, and at least a capacitor switch with a first end connected to the RC selecting switch and a second end floatingly connected to the capacitor output port. The second ends of the resistor switch and the capacitor switch are selectively connected to the resistor output port and the capacitor output port respectively for providing different combinations of a resistor output value and a capacitor output value.
