Analysis and synthesis of switched-capacitor circuits using switched-capacitor immittance converters

Switched-capacitor immittance converters (SCIC\´s) which are the switched-capacitor (SC) counterparts of GIC\´s are proposed. In this paper the definition and analysis of the SCIC\´s are given. Their fundamental properties are derived from the definition. Three methods for ladder simulation using the concept of SCIC\´s are presented. In the proposed bottom-plate stray-insensitive SCIC filter structure, only one operational amplifier is needed per node (excluding the grounded node) in the passive ladder network. This saving in the number of active elements is an advantage of this method especially in case of bandpass filter simulation.
