Re: LTspice non-inverting Opamp loop gain.
¿ªÔÆÌåÓýHi, Victor. Perhaps I should say 'Salve,
Victor'! I think you need to explain a bit more about your
question. What is it about the Tian method that you need more
information on? In the first place, with no external input, the
opamp doesn't 'know' whether it is inverting or non-inverting;
that is just a matter of how the external signal is fed in. In
the inverting case, it is fed through a resistor, but in the
non-inverting case, that resistor is between the inverting input
and ground, while the external input is applied, either via a resistor or directly, to the non-inverting input of the opamp, which may
have near-infinite internal impedance or a value defined in the
data sheet. On 2025-03-25 21:46, LV via groups.io
