HIGH RESOLUTION PULSE WIDTH MODULATOR |
摘要 |
<p>A pulse width modulator has a first clock source providing a clock signal to a set input of an output controller configured to set a pulse width output signal and having a reset input to reset the pulse width output signal. A duty cycle control unit is coupled with the reset input of the output controller, wherein the duty cycle control unit has a numerical controlled oscillator (NCO) being coupled with a register and configured to provide for a direct digital synthesis to produce a specified frequency according to a value set in the register. Furthermore, logic is provided for receiving a signal from a second clock source and the pulse width output signal to trigger the numerical controlled oscillator.</p> |
