H03K 4/71 with negative feedback through a capacitor, e.g. Miller-integrator
Introduced: January 1980
Title
Titles differ between systems:
IPC: with negative feedback through a capacitor, e.g. Miller integrator
CPC: with negative feedback through a capacitor, e.g. Miller-integrator
Full Title
Full titles differ between systems:
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 > using a semiconductor device operating as an amplifier > with negative feedback through a capacitor, e.g. Miller integrator
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 > using a semiconductor device operating as an amplifier > with negative feedback through a capacitor, e.g. Miller-integrator
No child classifications to compare. This is a leaf node in both IPC and CPC.
