Up to this point, we’ve shown how LTspice can implement a transfer function by using circuit elements and the Laplace transform. Examples shown have been in the frequency domain.

In a previous article (“Circuit Dynamics for Design”), we reviewed some of the mathematical properties of transfer functions in the s-domain and how generally to find the open-circuit time constants ...

A nonlinear parity–time-symmetric circuit is used to enable robust wireless power transfer to a moving device over a distance of one metre without the need for tuning.
