Abstract
A ring oscillator according to the invention includes a plurality of inverters cascade-connected between an input node and an output node. Each inverter includes four transistors connected in series between a power supply node and a ground node. A first pair of transistors each have a channel sized to have an input capacitance for delaying the signal of a preceding stage inverter for a prescribed time period. A second pair of transistors are coupled to a current mirror circuit and limits current flowing through the first pair of transistors. Thus, power consumption for obtaining a signal in a prescribed cycle is reduced.
