Abstract
A driving circuit includes a comparator that compares a voltage of an original driving signal with a voltage of a feedback signal of a driving signal, transistors, and a control signal generating circuit that generates a gate signal to the transistor and a gate signal to the transistor. The control signal generating circuit controls to alternately switch on the transistors. Driving abilities of the transistors are switched to be lowered by insertion of capacitors by an adjustment circuit.
