A new constant-current biasing technology has been proposed, analyzed, and applied to GaAs FET IC's using n-channel depletion-mode FET's. Current-mirror (CM) type current-sink (CS) circuits were proposed as a new building-block circuit. The monolithic prototype samples were fabricated, and ...
A current or voltage source is a supply of energy (such as a battery) capable of supplying energy into a load whose other terminal is connected to ground, whereas a sink may control the characteristics of an external source of energy, but provides none of its own. There are three important...
