Title:
SYSTEMS AND METHODS FOR GENERATING HIGH PERFORMANCE PULSE WIDTH MODULATION (PWM) SIGNALS
Document Type and Number:
Japanese Patent JP2019161648
Kind Code:
A
Abstract:
To generate a pulse width modulation (PWM) signal by a processor communicatively coupled to a system memory element.SOLUTION: A method computes, by a processor, a coarse adjustment PWM output signal and a modified fine adjustment input signal, by using a low speed clock rate; performs a fine adjustment to the coarse adjustment PWM output signal, by using a high speed clock rate, on the basis of the modified fine adjustment input signal; and generates an increased resolution PWM output signal on the basis of the fine adjustment.SELECTED DRAWING: Figure 6
