Parasitic-compensated building blocks for active switched-capacitor filters

The authors present novel stray-insensitive passive SC (switched-capacitor) building blocks which enable the realization of voltage transfer functions, voltage-to-current transfer functions, or the vector of voltage-to-current transfer functions. Such building blocks may be utilized in the synthesis of active SC filters. Circuits described by the voltage-to-current transfer functions may be used in the synthesis of SC networks comprising operational amplifiers, while the configurations described by the voltage transfer functions may be utilized in the design of SC circuits comprising unity-gain buffers. A number of design examples are provided.
