Stable frequency sawtooth oscillator |
摘要 |
A sawtooth-voltage-generating oscillator has a high gain comparator circuit formed of two differentially-connected NPN transistors driven respectively by two PNP transistors that leads to a very linear ramping of the sawtooth waveform, and at the same time, provides a sawtooth voltage swing at low supply voltages that may be within no more than 1.5 volts less than that low supply voltage. This oscillator also has the capability of working in the feed forward mode in a switching mode power supply while maintaining a stable oscillation frequency over a wide range of supply voltages.
