Voltage Controlled Duty Cycle Sawtooth Circuit

via till.com where you will find the full article.

"There was a discussion on synth-diy a while ago about the problems of building a voltage controlled oscillator with a sawtooth wave output whose duty cycle (the ratio of ramp-up time to ramp-down time) is adjustable with a seperate control voltage.

This is a very hastily written description of my proposal for a circuit that will implement this by warping the waveform of a regular sawtooth wave VCO."
