ABSTRACT:
A digital circuit includes a flip-flop for latching N-bit digital data for a predetermined period of time, a counter for cyclically counting N-bit binary data, a first adding circuit for adding n of LSBs of the N-bit digital data and n MSBs of the N-bit binary data and for generating first PWM data, and a second adding circuit for adding N-n MSBs of the N-bit digital data and N-n LSBs of the N-bit binary data and for generating second PWM data. The second adding circuit is capable of, in accordance with the first PWM data, adding on a time-divisional basis PWM data corresponding to a signal having a pulse width of T/2 (N-n) (T is a time period of one cycle) to second PWM data items which are generated by the second adding circuit.
