Abstract
An oscillation circuit includes a delay circuit that includes a first inverter having an input terminal connected to a first node, a delay adjustment circuit including first and second current supply paths through which the first node is charged in response to an output signal of the delay circuit. During charging of the first node, a current with positive temperature characteristics is supplied to the first node through the first current supply path, and a current with negative temperature characteristics is supplied to the first node through the second current supply path.
