I need a Sine Wave Oscillator circuit that can allow me to control its frequency with a microcontroller. Until now all the topologies that I have found if the frequency is changed, a change in the ...

I want to find the conditions of oscillation of the following Hartley oscillator.I have attached a load (ZL) to my Hartley oscillator I have written KCL for nodes A,B: For node A: $$\frac{V_{A...

I have been trying to model this oscillator I was wondering if we can somehow predict the frequency of the oscillations.For small currents inside a diode from the Shockley diode equation $$ e^{x...

I am trying to find the AC analysis of a BJT Hartley oscillator but I cannot continue. How do I find the voltage gain? When no feedback is there, we just find the output resistance and the current...

I have a 30MHz TCXO circuit (TXCO datasheet) like this serving as local oscillator to a RFIC: The RFIC manufacturer recommends to "add filtering caps" for high RF output cases. That is >20d...

Here is a video of the AN/PRM10, and here is a schematic (I believe the image can be zoomed): As most commercial grid dip meters produced in the past, this one possesses several functions in ad...
