Abstract
PURPOSE:To obtain a pulse width modulation output signal with less pulse uneven distribution by providing a 2nd comparator circuit receiving the weight of each digit of a high-order n-bit of a free run counter while revising in a prescribed order and comparing it with a low-order n-bit of an input data. CONSTITUTION:A 1st comparator 4 comparing the low-order n-bit of the free run counter 2 with the high-order n-bit of the input data and outputting a 1st binary signal, and the 2nd comparator 3 comparing the high-order n-bit of the free counter 3 with the low-order n-bit of the input data while revising the weight of each digit of the high-order n-bit in a prescribed order and outputting a 2nd binary signal are provided. Thus, the 2nd binary signal is the result of pulse width modulation of the low-order bit data of the input data and is located between the two 1st binary signals, then the uneven distribution of the pulse width modulation signal of the output is prevented.
