AI Thread Summary
To amplify a 2 MHz signal of 80 mVp-p for ultrasound sensors, a minimum gain of 10 is required. Standard operational amplifiers may not be suitable for this frequency, so specialized ICs or pre-built amplifiers are recommended. Products like the AD8250 instrumentation amplifier and Texas Instruments' OPT101P transimpedance amplifier are suggested as potential solutions. Mini-Circuits also offers a range of pre-built amplifiers that could meet the frequency requirements. Selecting the right amplifier is crucial for effective signal amplification in ultrasound applications.

i am working on ultrasound sensors. At the receiving end i have 2 MHz signal of 80 mVp-p. i need to amplify it at-least by 10 times. Pleases suggest me an appropriate method.

Additionally, i need to know if normal opamps work in 2 MHz signal? if not, are separate ICs available for that?

please give your suggestions friends.

with regards, palani.

The company Mini-Circuits has a wide variety of pre-built amplifiers for many frequency ranges:

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...
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...
