Abstract

An oscillation circuit that improves the duty controllability by cross-coupling ring oscillators that are comprised of current inverters. The sources of current supply circuits 4a-4c and 6a-6c are connected to a power supply and their drains are connected to terminals A in corresponding current inverters, respectively. Each of the gates of those current supply circuits receives an output of a current inverter corresponding, one to one, to a current inverter to which the current supply circuit is connected.
