Half of 7413 dual four-input NAND Schmitt trigger forms RS bistable which ensures that cycle is completed after switch is opened. Low-impedance exponential sawtooth output is produced at point C.Point A is high when oscillator is running and can be used as control signaL-T. P. Hopkins, Improved Schmitt Trigger Oscillator, Wireless World, Jan. 1978, p 58.
