WebIn 2024, Harper left the California Endowment to step into her current role as the Director of California TRANScends. This statewide initiative … 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 sometimes is, a varying signal current. Conceptually, an ideal current mirror is … Ver mais There are three main specifications that characterize a current mirror. The first is the transfer ratio (in the case of a current amplifier) or the output current magnitude (in the case of a constant current source CCS). The second … Ver mais For small-signal analysis the current mirror can be approximated by its equivalent Norton impedance. In Ver mais 1. ^ Keeping the output resistance high means more than keeping the MOSFET in active mode, because the output resistance of real MOSFETs only begins to increase on entry into the active region, then rising to become close to maximum value only when … Ver mais • 4QD tec - Current sources and mirrors Compendium of circuits and descriptions Ver mais Basic idea A bipolar transistor can be used as the simplest current-to-current converter but its transfer ratio would highly depend on temperature … Ver mais • Current source • Widlar current source • Wilson current mirror • Bipolar junction transistor • MOSFET Ver mais
