Open the CIPO recordAbstract From the Canadian patent
A triangle waveform generator is provided with a compensation network to eliminate the effects of frequency and amplitude errors caused by switching-control loop delays of the system. This is achieved by causing early switching of an amplitude-limit sensing detector so that the generated triangle waveform reverses polarity at the correct level. The compensation network may be implemented to accommodate independent ramp rates.
