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 ...
Using CMOS gates to generatepulses sometimes causes timinguncertainty due to gate-threshold variations.For accurate pulse widths, youcan use BJTs (bipolar-junction transistors).Basing the design on ...
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 ...
Over on his YouTube channel [Aaron Danner] explains biasing transistors with current sources in the 29th video of his Transistors Series. In this video, he shows how to replace a bias resistor (and ...
If you got your start in electronics sometime after 1980 your first project might well have been to light up an LED. Microcontroller projects often light up an LED, too, and a blinking LED is ...
A recently filed patent (Publication Number: US20230314495A1) describes a capacitance measurement circuit that includes an analog front-end circuit, a parasitic capacitor, an analog to digital ...
