For applications that require or desire a computer controlled variable current, the use of a digitally controlled potentiometer and a current mirror with degeneration provides a low cost solution. One ...
Recently (5/21/25), I published a Design Idea (DI) describing a bidirectional current mirror using just two transistors and a diode, “A two-way mirror—current mirror that is.” That circuit works well ...
CMOS current mirrors are pivotal in modern electronic circuitry, providing accurate current replication that is essential for biasing, amplification and active loading in a myriad of integrated ...
