How to Eliminate Parasitic Capacitance [message #165523] Thu, 21 April 2016 20:44 Go to next message

I have a circuit design that's highly influenced by parasitic
capacitance. I need advice on how to design my PCB to minimize parasitic
capacitance. I've attached the schematic. There will also be a
potentiometer where M3, M4, and M7 meet to help balance this circuit.

Thanks,
Mike [Op Amp 2.jpg]

I think I liked it better when the link wasn't working.

Read http://www.ti.com/lit/an/sloa013a/sloa013a.pdf to understand the
problem and ways to cope. But minimize circuit lead length and width of
leads.
