Abstract
A ramp waveform generating apparatus generates a reference waveform by using an input signal and generates a driving control signal for turning on and off a switch having a first terminal connected to a load and a second terminal connected to a power supply by comparing the voltage of the reference waveform with the voltage of the load. While the switch is repetitively turned on and off in accordance with the driving control signal, a ramp waveform may be generated.
