ABSTRACT:
A sawtooth generator for producing a sawtooth voltage of constant amplitude, comprising a transistor having, in the emitter lead, a resistor in series with a capacitor, a switch being in parallel with this capacitor. A second capacitor is included between the base and the junction point of the resistor and said first capacitor. A high-value resistor is connected between a d.c. voltage source and the base. The generator can also be made self-oscillating.
