Let us get down to basics. Conceptionally, a ring oscillator is a deceptively simple self-oscillating electronic oscillator that consists of a series of several inverters, where the output of each ...

The circuit in Figure 1 seems utterly simple but demonstrates unusual behavior. It produces an almost square wave of odd-integer quartz harmonics, including its main frequency. You can determine the ...

A few months ago we brought you some experiments from [Bill Meara, N2CQR], in which he investigated the use of a glue stick as the former for a permeability tuned inductor. His set-up was very much in ...
