Abstract :
In this paper, the operational-amplifier-free design of MOS active switched capacitor filters based on LC ladder simulation is explained. The integrators required in the simulation use the bucket-brigade charge transfer principle to avoid the use of operational amplifiers. The filters designed using this new technique are compatible with digital NMOS technology and require only a single power supply.
