DEFINITION

Classification: 326/77

ECL to/from MOS:

(under subclass 75) Subject matter comprising the interfacing between an emitter-coupled logic device and a metal-oxide semiconductor device.

(1) Note. An emitter-coupled logic device is a nonsaturated bipolar logic device in which the emitters of the input logic transistors are coupled to the emitter of a reference transistor.

(2) Note. A MOS device is a field-effect transistor that has a metallic gate insulated by an oxide layer from the semiconductor channel.
