Why does LT Spice simulation of AD711 op-amp show a non-zero output voltage when inputs not connected?
I am studying designing circuits. I got a strange problem with LT Spice.
I didn't connect any inputs into the amp but the result showed output...
I couldn't understand why it had the output voltage.

LTspice and ngspice simulation results differ by 5-6GHz
I simulated a basic CMOS inverter based 3 stage ring oscillator in both LTspice and ngspice, using the same model files (using NCSU's freepdk45 models (VTG slow slow corner)). I expected there to be ...

RC coupling or LC coupling
I would like to generate a signal composed of an AC waveform and DC voltage separately, with the AC frequency range being 20 Hz to 20 kHz.
I found there are two ways to achieve it: RC coupling and LC ...
