Abstract
An electrical circuit assembly includes a node and an electrical circuit. The circuit draws a node point to a specific potential when and for as long as the node point is not drawn in any other way to a different potential. The electrical circuit is distinguished by the fact that the electrical circuit operates as a function of the potential at the node point. In other words, the potential to which the node point is drawn by the electrical circuit can be varied by a weak signal, but not also just by electromagnetic interference.
Claims25
An electrical circuit assembly, comprising:
- a node supplying a potential;
- and
- an electrical circuit drawing, dependent upon the potential at said node, said node to a given potential when and for as long as said node is not drawn in any other way to a different potential.
