METHOD AND APPARATUS FOR GENERATING A MODULATED WAVEFORM SIGNAL

摘要

A semiconductor device comprising timer logic for generating a first modulated waveform signal, and delay logic, operably coupled to the timer logic and arranged to provide a first delay in a rising edge of the first modulated waveform signal generated by the timer logic; and provide a second delay in a falling edge of the first modulated waveform generated by the timer logic. The first delay and second delay of the first modulated waveform forms a second, refined modulated waveform signal that comprises a higher frequency resolution than a frequency resolution of the first modulated waveform signal.
