H03K 4/52

using two semiconductor devices so coupled that the input of each one is derived from the output of the other, e.g. multivibrator

Introduced: September 1968

Full Title

Full titles differ between systems:

IPC:

Generating pulses having essentially a finite slope or stepped portions > having triangular shape > having sawtooth shape > using as active elements semiconductor devices > in which a sawtooth voltage is produced across a capacitor > using two semiconductor devices so coupled that the input of each one is derived from the output of the other, e.g. multivibrator

CPC:

Generating pulses having essentially a finite slope or stepped portions > having triangular shape > having sawtooth shape > using as active elements semiconductor devices (H03K4/787 - H03K4/84 take precedence) > in which a sawtooth voltage is produced across a capacitor > using two semiconductor devices so coupled that the input of each one is derived from the output of the other, e.g. multivibrator
