Steady-State Analysis of Linear Networks Containing a Single Sinusoidally Varying Capacitor

In this paper a method is presented for analyzing linear time-invariant networks containing a single sinusoidally varying capacitor. The method is based on difference equations, and yields an explicit expression for the steady-state response. Error bounds are given whenever approximations are made. A numerical example is included in order to compare the method presented with the Harmonic-Balance method.
