"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 simply an ideal inverting current amplifier that reverses the current direction as well or it is a current-controlled current source (CCCS). The current mirror is used to provide bias currents and active loads to circuits. ...
Basic BJT current mirror.
If a voltage is applied to the BJT base-emitter junction as an input quantity and the collector current is taken as an output quantity, the transistor will act as an exponential voltage-to-current converter. By applying a negative feedback (simply joining the base and collector) the transistor can be "reversed" and it will begin acting as the opposite logarithmic current-to-voltage converter; now it will adjust the "output" base-emitter voltage so as to pass the applied "input" collector current.
The simplest bipolar current mirror ... implements this idea. It consists of two cascaded transistor stages acting accordingly as a reversed and direct voltage-to-current converters." [Current mirror. Wikipedia]
The circuit diagram example "Bipolar current mirror" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Electrical Engineering solution from the Engineering area of ConceptDraw Solution Park.

This solution extends ConceptDraw DIAGRAM.9.5 (or later) with electrical engineering samples, electrical schematic symbols, electrical diagram symbols, templates and libraries of design elements, to help you design electrical schematics, digital and analog

Electrical Drawing Software and Electrical Symbols

Any electrical device could not be created without electrical diagram, wiring also cannot be laid without pre-designed and approved scheme or plan. Electrical drawing is a type of technical drawing that depicts scheme of some electrical device and includes the information about power, lighting, etc. Electrical plan designed for architectural or engineering project visually displays location of electrical devices and connections. ConceptDraw DIAGRAM is ideal electrical software for construction professional-looking Electrical Circuits, Electrical Schematics, Electrical Layouts, Electrical Wiring, Automotive Wiring, Cabling Layout Diagrams, Circuits and Logic Schematics, Logic Gate Diagrams, Digital Circuits, Parallel Circuits, Blue Prints with help of 926 standard electrical symbols offered by 26 libraries of Electrical Engineering solution from the Engineering area for ConceptDraw DIAGRAM. It makes drawing Electrical diagrams very easy even for beginners, and also extends your work with various export methods.

Electrical Schematics

ConceptDraw DIAGRAM diagramming and vector drawing software extended with Electrical Engineering Solution from the Industrial Engineering Area of ConceptDraw Solution Park affords you the easiest and fastest way for designing professional looking Electrical Schematics.

Electrical Symbols, Electrical Diagram Symbols

Electrical Diagram Symbols
When drawing Electrical Schematics, Electrical Circuit Diagrams, Power Systems Diagrams, Circuit and Wiring Diagrams, Digital and Analog Logic Schemes, you will obligatory need the electrical symbols and pictograms to represent various electrical and electronic devices, such as resistors, wires, transistors, inductors, batteries, switches, lamps, readouts, amplifiers, repeaters, relays, transmission paths, semiconductors, generators, and many more. Today these symbols are internationally standardized, so the diagrams designed using them are recognizable and comprehensible by specialists from different countries. Electrical Engineering Solution included to ConceptDraw Solution Park provides 26 libraries with 926 commonly used electrical schematic and electrical engineering symbols making the reality the easy drawing of Electrical diagrams, schematics and blueprints. Now you need only a few minutes to create great-looking Electrical diagram, simply choose required electrical design elements from the libraries, drag them on the needed places at the document and connect in a suitable way.

How to Resize Objects

When creating diagram using ConceptDraw DIAGRAM , you can select, move, resize and rotate objects. After selecting an object (or objects) in a document, you can change it position, resize it or move an object to the desired position. The sizes of objects in ConceptDraw DIAGRAM can be changed by simple dragging, or you can set a particular size of any object. Using ConceptDraw PRO, you can re-size an object on the page using the absolute measurements instead of a mouse. You can make quick work of designing complex drawing using a combination of different-sized items.
