Abstract

A CMOS digitally programmable lossless floating inductor is proposed. The proposed inductor is based on current conveyors and resistor array to provide digital tuning of the inductance value. The presented block realizes a programmable floating inductor tuned from 0.42763 mH to 5.67 mH. As an application for the proposed circuit a resonant circuit and low pass filter have been realized using the digital programmable circuit. The simulation results have been demonstrated and discussed using a SPICE simulation for 0.25 μm TSMC CMOS technology and supply voltages ±1.5 V.
