DEFINITION

Classification: 505/857

Nonlinear solid state device system or circuit: (Class 307/200+):

(under subclass 856) Subject matter whose specific function is not provided for elsewhere comprising circuits or devices which include solid state devices or components through which charge carriers are conducted, the current versus voltage characteristic of such device or component being nonlinear.

(1) Note. This definition excludes linear resistors, capacitors, inductors, etc.
