Transistor ∆VBE-based oscillator ... transistor in this diagram, I don’t see how it could be “unnesessary” since the circuit wouldn’t work without it. Log in to Reply. WStephenWoodward December 29, ...

CNT-based PTL circuits. A popular and widely used alternative to the conventional CMOS logic configuration is the PTL configuration, which can significantly reduce the number of transistors ...

The transistor can never be saturated or be in cut-off. In the lower circuit, having the emitter follower is beneficial. Apart from protecting the oscillator from being quenched by some external load, ...

I remember making a flasher with a LM3909 back in the late 1970s. It was very efficient. In regards to this circuit, I can think of one that is even simpler, although not so stable.

Finally, for the first time, ring oscillator circuits were reported based on stacked silicon nanowire FETs, including dual work function metal gates for threshold voltage control. Imec has also ...
