Current mirror — A current mirror is a circuit designed to copy a current through one active device by controlling the current in another active device of a circuit, keeping the output current constant regardless of loading. The current being copied can be, and… … Wikipedia
Open drain — is one of the many different electrical input/output standards in digital designs today. Definition The word drain in the term Open drain refers to the drain terminal of a MOSFET transistor. (The analogous term for BJT devices is open collector.) … Wikipedia
Common drain — In electronics, a common drain amplifier, also known as a source follower, is one of three basic single stage field effect transistor (FET) amplifier topologies, typically used as a voltage buffer. In this circuit the gate terminal of the… … Wikipedia
