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, ...
Lively discussions have sprung up here in editor Aalyia Shaukat’s Design Ideas regarding the limitations and quirks of, and design tricks for, the current control topologies shown in Figure 1. Figure ...
