发明名称 Sawtooth oscillator
摘要 <p>A sawtooth generator circuit comprises a first triangular waveform generator with equal ramp up and ramp down rates and a second triangular waveform generator with equal ramp up and ramp down rates and which are equal to the ramp up and ramp down rates of the first triangular waveform generator. The first and second triangular waveform generators are controlled to be 180 degrees out of phase. A switching arrangement alternately switches the increasing or decreasing ramps of the first and second triangular waveform generators to an output of the sawtooth generator circuit. The invention provides a sawtooth generator circuit which is suitable for high frequency applications, with low current consumption and low ground bounce. A very fast falling edge can be obtained.</p>
