Abstract
A drive signal supply device includes an oscillation circuit, a drive signal generation circuit, and a control circuit. The oscillation circuit includes a plurality of oscillators each including inverters and outputs a plurality of oscillation signals. A switching characteristic of each of the inverters included in one of the plurality of oscillators is different from a switching characteristic of each of the inverters included in another of the plurality of oscillators. The control circuit detects a process corner of the semiconductor device based on the plurality of oscillation signals to generate a control signal. The drive signal generation circuit generates a drive signal of a semiconductor device based on the control signal.
