Abstract

A CR oscillation circuit includes an oscillation unit having first through third invertion circuits connected in series between a first node and a second node, a capacitance element provided between the first node and an output terminal of the second inverting circuit, and a switch part for electrically connecting the first and second nodes according to a level of a control voltage; a constant current unit for allowing a constant current to flow according to a resistance value of an externally-provided resistive element to thereby supply a constant voltage; and a level conversion unit for converting a level of the constant voltage to thereby produce the control voltage.
