This design idea reprises another “1A, 20V, PWM controlled current source.” Like the earlier circuit, this design integrates an LM3x7 adjustable regulator with a PWM DAC to make a programmable 20 V, 1 ...
CMOS current reference circuits play a critical role in modern integrated circuits by providing a stable and reproducible current source that remains unaffected by variations in supply voltage, ...
Vactrols, or both an LED and a light depending resistor (LDR) in a light-tight housing, are found in analog music electronics circuits like audio compressors, voltage-controlled amplifiers (VCAs), ...
