in which a sawtooth current is produced through an inductor

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 current is produced through an inductor

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 current is produced through an inductor

IPC and CPC are identically structured here. All 2 subcodes exist in both systems.
