Here is a simple frequency doubler circuit that produces a square wave output with a precise 50 percent duty cycle. There are similar circuits in the literature [References 1, 2, 3] which require ...

The versatile phase-locked loop (PLL) allows multiplication of a reference frequency with an operating frequency that ranges from “DC to daylight.” A PLL is overkill for some applications, however, ...

American manufacturers are importing European and Asian industrial equipment at an accelerating pace. The problem: that ...

For a long time, I have thought that pulse generator outputs should not have adjustable amplitude and offset. Instead, they should have an adjustable top value and a separately adjustable bottom value ...

Last time on Circuit VR, we looked at creating a very simple common emitter amplifier, but we didn’t talk about how to select the capacitor values, or much about why we wanted them. We are going to ...

Engineers have crafted the world's highest-frequency circuit made with a common type of semiconductor transistor, a step that could slash the price of detectors useful in earlier cancer detection and ...
