DEFINITION

Classification: 327/535

Having stabilized bias or power supply level:

(under subclass 534) Subject matter wherein the bias or power supply level provided to the substrate of a nonlinear element or solid-state device is maintained constant.

(1) Note. The stabilization may be for either voltage or current level to compensate for adverse conditions (e.g., nonuniformity of integrated chip structure, supply level perturbations, etc.).
