Subject: [LTspice] Re: Need help to design a transimpedance amplifier? ? Let me say why am looking for new design..
We are currently using the receiver module which has three stages:
1. Trans Impedance stage
2. High Pass filter (HPF) stage
3. Unity gain amplifier (just for inverting the output of the HPF)
Well...we used LM2662 as a -5V supply..
Here on we could see the hell noise below 100kHz..
I couldn't get rid of this noise by using bypass caps..but I could just reduced it..
Yet there is a lot of noise all across the circuit ranging from few kHz to hundreds of MHz...
are the links where I have uploaded couple of documents..
I really don't know what sort of noise it is and from where it is coming...
