AI Thread Summary

The discussion focuses on determining the gain of a JFET differential amplifier circuit, specifically how to calculate V1 and VD2. It is suggested that VD2 can be expressed as gm multiplied by RD, assuming rd is infinite. However, the original poster forgot to attach the relevant file for further clarification. The conversation emphasizes the need for accurate calculations in understanding the circuit's performance. Overall, the thread highlights the complexities involved in analyzing JFET differential amplifiers.

Please refer to file attached. I'm trying to understand how to find the gain for the JFET differential amplifier circuit, My guess is that vd2 is gm*RD. rd=infinity in this case. How do you find V1?

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
