    Why doesn't my circuit oscillate?

    First, sorry for my bad english. I'm building a project using a Colpitts Oscillator with Differential Pair, designed for ~117.6MHz. I'm using LTspice for simulation. The oscillator individually oscillates, but I need it to oscillate when I add a sensor model (as seen in the image in the...

    What Colpitts oscillator is this?

    Hi everyone. I've come accross an oscillator circuit (first attached image, left), which is very similar to a common collector crystal Colpitts oscillator (right). But it is not a common collector, as the load (hf transformmer) is placed in the collector node and output is taken from there. Not...

    Cycle-to-cycle jitter on Colpitts oscillator

    Hi there I'm struggling to get rid of jitter on my Colpitts oscillator. It is currently oscillating at 15 kHz. The problem is that I am getting cycle-to-cycle jitter of up to 384 nS. Is it possible to get a lower cycle-to-cycle jitter with this kind of oscillator. What is a typical...
