Abstract
An oscillator includes first, second, and third current sources, a resistor having first and second terminals, first and second capacitors each having first and second terminals, a switch circuit through which each of the current sources is connectable to the first terminal of one of the resistor and the two capacitors to supply current thereto, a comparator, and switch controller configured to generate control signals for the switch circuit and an oscillation output signal for each of multiple periods based on an output signal from the comparator. During one of the periods, the switch circuit is controlled to connect the first current source to the first terminal of the first capacitor, the second current source to the first terminal of the resistor, the first terminal of the resistor to a first input of the comparator, and the first terminal of the first capacitor to a second input of the comparator.
