Current mirror bipolar

Compact black textbook-style schematic of a basic two-transistor bipolar current mirror using two matched BJT, typically NPN, symbols side by side in a clean symmetric layout. The bases are tied together, and one transistor is diode-connected by shorting its collector to its base to create the reference branch. The second transistor shares the common base node and provides the mirrored output current at its collector. The emitters are tied together to a common supply rail, with crisp black schematic lines on a white background and minimal labeling, clearly recognizable as a classic analog current mirror building block.
