[Martin] sent in a great guide to a simple Arduino based theremin. It’s a very small build – just a single common IC and some passive components – and easy enough to build in an afternoon. The ...
Abstract: In this work, we investigate, for the first time, a low phase noise and wide tuning range voltage-controlled surface acoustic wave oscillator (VCSO) based on a lithium niobate on sapphire ...
Abstract: A low electromagnetic interference (EMI) isolated dc-dc converter with a cross-coupled shoot-through-free Class-D oscillator and a voltage series-combining transformer is presented. The ...
