Abstract
An oscillator of the present invention includes a constant current circuit in which a constant current generated in the constant current circuit varies positively with an on threshold voltage of a transistor included in the constant circuit; and an oscillating circuit in which the oscillating frequency of a clock signal generated in the oscillating circuit varies positively with the constant current supplied from the constant current circuit, and the oscillating frequency of the clock signal generated in the oscillating circuit varies negatively with an on threshold voltage of a transistor included in the oscillating circuit.
