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 ...
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 ...
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 ...
