Techniques - Pulse biased oscillators

[Teleno]

I wonder how many of you know what a pulse bias oscillator is. Keywords: spectral purity, low 1/f noise.

Let's discuss a practical implementation.

Also called Pulse Energy Restore Oscilators. https://www.researchgate.net/publica...ore_Oscillator

It is assumed that the best time instant for the energy restore pulses is when the voltage at the LC tank is at its peak (maximum, minimum or both).

A circuit implementation would require a fast pulse generator synchronized to the phase of the oscillations.
An implementation would require for energy restore is when the voltage across each TANK is
at its ma

First challenge for an implementation: a high side current pulse generator.

Here's my idea. Who wants to brainstorm?

The good thing about this concept is that 1/f noise is completely gone. Such an oscillator makes possible sensitive detection by the tank loading effect.
