thanks for the help so far.
i was hoping to use this circuit at low voltages <1V, so a 0.1V offset might be an issue. is there anything i can do to remove this bias?
my simulation software says that a tl081 has:
input V offset: 5m
input I bias: 30p
input I offset: 5p
in practice i...
the circuit is a controller so the desired response is just the step response - however, its only required over a short period so ive attached a new desired response. on my simulation of the "real" circuit, i had forgotten to add a ground so that was causing part of the problem.
The...
using an ideal opamp in the configuration shown, i get the 20mV step response as shown. if i use the tl81 opamp, the step response is completly different. can anyone suggest anything to enable me to get a better step response?
thanks

hi guys, 1st post so please be gentle :) ive had a quick search but cant find a definate answer.
im trying to build a 741 opamp with a gain of 1k.
its wired up as per the diagram with both offset pins grounded, and supplies of +-15v
if i supply the device with +-10mV square wave, im...
