Group delay and group delay sensitivity of periodically switched linear networks

This paper presents a method for the computation of group delay and group delay sensitivity of periodically switched networks containing all types of linear elements. The method is accurate because no approximation is made, and efficient because some parts of the computations are performed only once, in a preprocessing step before simulation starts. The method can be used for analysis of switched-capacitor (SC) and switched-current (SI) filters where resistances of the switches, or frequency dependence of the amplifiers cannot be neglected.
