Re: low noise amplifier for high impedance source

Hi Marte,
Thanks for replying. Here i have the fundamental paper talking about
the electrical model of my detector by Comisarow, which is a penning
trap. I

ts based on rotating monopole and in Fig. 3 and 4 the schematic is
presented. I base almost all of my design thoughts on this paper.
Also, thanks for the TI reference. I found one of the AN disucssing
noise comparison of TIA and switched integrator.
Please let me know of your thoughts regarding the source modelling.
