AI Thread Summary
The discussion focuses on converting an OpAmp-based integrator filter to an OTA-C (Operational Transconductance Amplifier-Capacitor) version while maintaining the same behavior. The user seeks guidance on how to translate the resistor-capacitor (RC) values from the OpAmp design to the OTA-C configuration. Clarification is provided that OTA refers to an operational trans-impedance amplifier. The conversation highlights the need for understanding the differences in circuit behavior between the two types of integrators. Overall, the thread aims to assist in achieving equivalent performance in the transition from OpAmp to OTA-C.

I have a fliter that uses OpAmp based integrator. I want to make the same filter but using OTA-C instead of opamps. But I'm confused on the process of doing that. Anyone can help me on how to get the same behavior from the transition from one to an other?In other words translating the RC values in the omAmp version into the OTA version with the same behaviour

The ota will be a simple differential pair with resistors as loads.

Welcome to the PF!

What's an OTA? What is the context of the question? (School project, personal project, etc.)

OTA: I mean operational trans-impedance amplifier.

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...
