GROUND CONTROL PI CIRCUIT

Hi George, I spent plenty of time testing both options, but the best method for GB and EF cancel is to use the single ended integrator method. It works better for wide samples.

That's good to know. Practical experiments are what counts.

Hi Bruce, yeah going good, spending time out detecting yellow stuff...

Great to hear you are finding some yellow, we have had 120 days of virus lock down and being stuck at home has not been much fun, hoping to get out for a bit , but I see its getting a tad warm up north now.
So the single ended integrator method is the way to go, thanks.

Talking about one integrator method. Anybody had oscillation at the output of inverting amplifier stage?

Which circuit did you build ?

[Vadim18]

Integrator stage from D.P. I guess this oscillation coused by oscilloscope probe, by capacitance.

Yeah this covid19 stuff is bad but at least Vic is on the tail end of it.

Do you still have any pics of the front end I'm using ?

G'day Mick I have one from 2015, but I think it was experimental with blocking fets.

Yeah I'm not using that design anymore.

I'll see if I have a circuit of the new front end at some stage...

Thanks Mick.

G'day Mick did you have any luck finding that circuit , thanks.

Hi 6666,

No I'll have to redraw it at some stage. Everything is packed away at the moment. The last few months have been busy, including moving and getting Married....

But soon I'll have the work bench setup and I have a few new ideas to tryout also.

No worries Mick sounds like a busy time, congrats on getting married
