#104: Circuit tutorial: sawtooth generator w/ current sources, diode switches, hysteresis comparator

This circuit tutorial discusses a simple adjustable sawtooth waveform generator that features constant amplitude and independently adjustable rising and falling edges. The circuit uses simple current sources, a neat little diode ring electronic SPDT switch, and a comparator with hysteresis. Each of these circuits is described, and the overall circuit is presented along with waveforms from the various nodes in the circuit. A PDF file of the drawings in this video can be found here:
