The Laplace transform allows us to describe how the RC circuit changes both gain and phase over frequency. The example file is Simple_RC_vs_R_Divider.asc . 1 Laplace Transform Syntax in LTspice ...

A step-function input voltage causes an input current of V IN /R G, and the input current could damage the capacitor, damage the op amp, or cause ringing. Engineers often put a small resistor in ...
