    SAW Sensor - Why is my circuit not oscillating?

    First, sorry for the bad english. It's not the first time I've been looking for help on this circuit on the forum. I'm from Brazil, I'm doing a university project using which basically consists of using a colpitts oscillator with differential pair, with a SAW sensor in its feedback loop. The SAW...

    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...
