Document Type and Number:
Japanese Patent JP5320975
Kind Code:
B2
Abstract:
A pulse width modulation circuit includes: a reference signal generator which generates a plurality of mutually differing reference signals; a comparator which compares the reference signals and an input signal with respect to magnitude, and outputs results of the comparison as a plurality of comparison signals with mutually differing phases; and a synthesizer which, using a logical operation, outputs the plurality of comparison signals output from the comparator as a pulse width modulated signal configured of one or more binary signals.
