  • Power supply and DC-DC-conversion
    Patent number: 8686801
    Abstract: In an embodiment of a converter, a first oscillator provides switching signals for switching between charging and discharging of a capacitor, and a second oscillator is configured to add an offset voltage or a feedback-current-dependent voltage to a sawtooth waveform generated by the second oscillator switched in synchronism with the first oscillator.
    Type: Grant

  • Sawtooth oscillator
    Patent number: 8294496
    Abstract: 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.
