CMOS digitally programmable grounded inductor

摘要

A CMOS digitally programmable lossless grounded inductor is presented in this paper. It uses two digitally programmable second generation current conveyors (DPCCII) and three grounded passive elements including one capacitor only. The inductance value is tuned by programmable gain factor of current conveyor. As an application, a current mode multifunction filter has been realized using proposed programmable inductor. The simulation results have been demonstrated and discussed using a SPICE simulation.
