Title:
ディスクリートタイム発振器を利用したモータ駆動回路とその方法
Document Type and Number:
Japanese Patent JP4976869
Kind Code:
B2
Abstract:
A pulse width modulator includes a discrete time oscillator, a data storage device, a data processing block, a counter, and a comparator. The discrete time oscillator generates a first address of bits used by the data processing block for reading first data from the data storage device. The data processing block generates second data from the first data and at least one bit of the first address bits. The comparator generates a pulse width modulation signal by comparing the second data and a digital count generated by the counter.
