An ultra-low power sensor operates using energy harvesting from various sources for efficient monitoring. The oscillator ...

[Qrp-Gaijin] shows how to do it with a single transistor ... Changing the oscillator topology did the trick. A tuned circuit prevents the oscillator from having sufficient gain at the fundamental ...

You can find sample setups of a simple two-transistor LC-based Peltz oscillator ... and 10 without any changes to the component values or circuit, this is due to the subtle non-linearities within the ...

One of the first big improvements of this build style is the shift from the originally used spark gap commutator to that of a direct AC drive via a MOSFET oscillator. This improves the primary ...
