CMOS-BASED INTEGRABLE ELECTRONICALLY TUNABLE FLOATING GENERAL IMPEDANCE INVERTER

An integrable electronically tunable general impedance inverter (EGII) , implemented by a MOS circuit design technique, is described. The dri ving point impedance of the EGII, that is inversely proportional to a given impedance, can be a positive or a negative value and can be elec tronically varied. The realization scheme employs proposed voltage-to- current transducers (VCTs) that are designed based on a linearizing te chnique, as basic circuit building blocks. The applications of the EGI I as a gyrator, a general impedance converter and a floating capacitan ce multiplier are discussed. Experimental and simulation results that demonstrate the characteristics of the EGII are included.
