Digitally Controlled Current Limiter Safely Charges Large Capacitor Banks

At a power-on cycle, inrush current, if not limited, can peak to tens of even hundreds of amps when capacitive load is present, thereby increasing the probability of failure and decreasing usable ...

Building a JFET voltage-tuned Wien bridge oscillator

Since the derivation of the Wien network by Physicist Max Wien (prior work was the ballistic bridge by J. C. Maxwell) in 1891, this network has been used in many oscillators’ designs. One of the most ...
