Title:
PULSE SIGNAL GENERATING CIRCUIT AND PULSE SIGNAL GENERATING METHOD
Document Type and Number:
Japanese Patent JP2013211682
Kind Code:
A
Abstract:
To provide a pulse signal generating circuit capable of generating a highly precise PWM signal.
A PWM period adjustment part 400 generates a second count-up signal en2 by adjusting a count-up signal en generated by dividing a clock, on the basis of a set value of a PWPARL210 indicating an additional frequency widening a pulse period. A PWM waveform generation part 500 generates a PWM signal on the basis of the second count-up signal en2 and the predetermined duty ratio.
