Looking for charge amplifier users fC to pC charge CSP

08/12/2007 4:21 AM

Friends,

I have enough technology developed for different applications of charge amplifiers. Now I am Looking for charge amplifier users fC to pC charge CSP. If you are OEM integrator and want to discuss your application them you are welcome to ask questions.

You can have signal frequency domain and charge sensitivity requirements. Any other parameter also you can discuss. Lowest frequency is DC and highest frequency is 1GHz. Hence, I design these in specific frequency range for each application.

You can use these for piezo-electric transducer, capacitive ion beam current sensors, Faraday cup charge and current sensors, photo diode and photomultiplier tube charge amplifier, Micro channel plate and Channel electron multiplier amplifier.

I will welcome communication from engineers in research institutes and industries.

Good morning Shyam: I have developed and now marketing a system that requires an acceleration signal sampled at 100 kHz and with voltages from below 1 millivolt to 10 volts and frequencies from 3 to 30,000 kHz. Can we build that into a sensor? The sensor should have a resonance of approximately 20 kHz, small physical size and a modest cost.

What do you think? John Judd

Good that you have developed this technology. I think you should keep away from resonance frequency for such measurement and operate in much lower than resonant frequency band. This makes the sensor to work in damped condition to recover faster from shock wave or acceleration to zero acceleration.

Look for PCB or Kistler pressure transducer literation and you can learn lot from them.

Well, I feel good when some one is trying out to do something in technology.
