current mirror

[′kər·ənt ‚mir·ər]
(electronics)
An electronic circuit that generates, at a high-impedance output node, an inflowing or outflowing current that is a scaled replica of an input current flowing into or out of a low-impedance input node.

A single-ended output differential amplifier can be implemented by loading a PMOS current mirror on the top of the circuit of Fig.
The proposed topology includes an interesting power saving strategy in which a single NMOS cascode current mirror serves three functions simultaneously; it conveys X terminal current to Z output, provides high impedance at Z terminal and helps further reducing the X terminal impedance by establishing a negative feedback loop.
The output current is transferred by the two output cascoded current mirror (MOSFETs [M.sub.18], [M.sub.19], [M.sub.20], [M.sub.21], [M.sub.22], and [M.sub.23]).
The first stage is a single-ended differential pair with active current mirror load.
A current mirror CMOS circuit is integrated with an MTJ-STO element as shown in Figure 3.
For the current bias as the tail, a current mirror with a stable reference current, [I.sub.REF], can be employed in the integrated circuits to give a high output resistance, [R.sub.T].
The proposed mixer is based on a current mirror amplifier combined with passive switching core and minimizes the number of passive components.
The detector current is copied linearly and accurately to an off-pixel integration capacitor by the help of a current feedback structure implemented with a NMOS current mirror and a PMOS cascode current mirror.
