  We consider a special form of parametric generalized equations arising from
electronic circuits with AC sources and study the effect of perturbing the
input signal on solution trajectories. Using methods of variational analysis
and strong metric regularity property of an auxiliary map, we are able to prove
the regularity properties of the solution trajectories inherited by the input
signal. Furthermore, we establish the existence of continuous solution
trajectories for the perturbed problem. This can be achieved via a result of
uniform strong metric regularity for the auxiliary map.
  Key words and phrases: generalized equations, electronic circuits, strong
metric regularity, uniform strong metric regularity, perturbations.
