DEFINITION

Classification: 327/461

Inverse parallel connection:

(under subclass 460) Subject matter wherein two four or more layer devices are connected across each other, but in opposite directions (i.e., the cathode of one device is joined to the anode of the other device at one common node and vice versa at the other common node).
