Apparatus and method for driving a pulse width modulation reference signal |
摘要 |
An apparatus for driving a pulse width modulation reference signal includes: (a) A converting unit receiving an input signal at an input locus and presenting an output current at an output locus. The input signal varies at a first frequency. The output current is substantially related with the first frequency. (b) A capacitive element coupled with the output locus for charging by the output current. The pulse width modulation reference signal is related with voltage across the capacitive element.
