resistor placement in inverting amplifier to minimise noise coupling
(Image is my own creation.)
I notice that an inverting amplifier can be very sensitive to capacitive and inductive noise coupling on a PCB. I was wondering whether the placement of the R1 resistor ...

Current slew rate specification of op-amps?
I know that slew rate specifies how fast the output voltage of an op-amp can change. But is there a measure that specifies how fast the output current of op-amps can change?
I need this information ...

Does max OP Amp Capacitive Drive Capability Matter with Active Filter?
I know that every OP Amp does have a limited capacitive load drive capability.
Even if not specified, it is always a good practice to use a series isolation resistor.
Anyway; when looking at an active ...

How to know if an opamp can drive capacitive loads?
There has been a lot of questions about how to stablise opamp circuits driving capacitive loads. However, I know there are some op amps that are designed to drive capacitive loads but I am struggling ...

How to properly drive parallel analog switches (variable capacitive loads) with opamp(s)?
So as you can see I have 16 SPDT switches on one side of my 16 'RUT paths' and 16 SPDTs on the other side. Each SPDT(ADG1434) has two source pins (SXA and SXB) and a common drain pin (DX), 'X' ...

How to make sure that my compensated attenuator would work for certain pulse widths?
I have an input (one-shot) pulse that has to be attenuated by 1/2 (half). The input pulse would be of variable width in between 1us and 100ms and would have a variable amplitude: one voltage level ...

Stability - Driving a Capacitive Load
I know I have been asked not to provide video links and ask questions.
But I have no proper guide/mentor or anyone who can provide me better answers other than users in this site. So, please pardon ...

Capacitance on the output of an op amp
I have read a lot about capacitive loads on the output of an op-amp and the possibility of unwanted oscillations and instability. my knowledge on phase margin and frequency domain analysis is a little ...
