Editor’s note: Recently, Tamara Schmitz and Mike Wong of Intersil Corp authored a three-part series in Planet Analog on the basics of bypass capacitors, entitled “Choosing and Using Bypass Capacitors.
A pulse-width-modulated (PWM) signal and the RC-charging characteristics of a weighted-capacitor network can be used along with a CMOS Schmitt inverter to generate a pulse whose width is linearly ...
A snubber circuit limits voltage spikes in power converters. Snubbers are also used in the output of Class-D audio amplifiers for the same reasons (Fig. 1). When the transistor you use to switch the ...
