Everyone interested in analog electronics should find some value in this post. Of course, an effort has been made here to make the content understandable to relative newbies. Forget about complex ...

Sine waves are beneficial for information interchange, e.g. they have very a short and predictable frequency spectrum. When needed, it is relatively easy to suppress the sine signals with filters. On ...

We needed a handheld, battery-powered signal generator with a sine-wave output that was continuously adjustable from 100 Hz to 10 kHz. For such a wide frequency range, we selected a function-generator ...

Fig 1. Two analog multipliers form a VCO with quadrature outputs, while a third multiplier provides AGC to stabilize output voltages without adding distortion. Fig 2. The oscilloscope trace of the VCO ...

Current‐mode amplifiers have emerged as a highly efficient alternative to traditional voltage‐mode systems, particularly in high frequency and low power electronic applications. Their ability to ...
