Abstract:
1. A waveform generator circuit, comprising: a triangular and pseudo-sinusoidal waveform generator adapted to accept clock signals and generate triangular waveforms; an amplitude control current responsively coupled to the triangular and pseudo-sinusoidal waveform generator operable to control the amplitude of the generated triangular waveforms; a reference voltage circuit responsively coupled to the amplitude control circuit, operable to generate reference voltages for the peak voltages of the triangular waveform; the triangular and pseudo-sinusoidal waveform generator operable to accept one or a plurality of clock signals; the triangular and pseudo-sinusoidal waveform generator further operable to generate triangular waveforms from the clock signals, the triangular and pseudo-sinusoidal waveform generator further operable to rectify the triangular waveforms; the triangular and pseudo-sinusoidal waveform generator further operable to smooth the triangular waveforms into pseudo-sinusoidal waveforms.
