Re: Active electrode - capacity, resistance

Hi,

As mentioned:

The result is a very high impedance (ca. 90 GigaOhm at 50Hz, see attached
spice simulation and picture).
This technique is also know as bootstrapping or in other context: active
shielding or guarding.

would you please send the spice simulation and reference for the bootstrapping?

Best, 
Yicheng
