Abstract
A driving circuit includes a reference voltage generating circuit and a driver circuit. The driver circuit drives a driven element at a level determined by the reference voltage output by the reference voltage generating circuit. The reference voltage generating circuit includes a regulating section that generates a regulated voltage, a temperature compensation section that applies a temperature compensation to the regulated voltage to compensate for the temperature characteristics of the driven element, and a voltage amplifying section that amplifies the resulting temperature compensated voltage to generate the reference voltage, thereby supplying a reference voltage high enough to avoid noise effects.
