RECONFIGURABLE FLOATING IMPEDANCE USING SINGLE DIGITALLY PROGRAMMABLE CMOS DVCC

A general scheme is presented to convert any grounded impedance into reconfigurable floating impedance using single digitally programmable CMOS differential voltage current conveyor without any component matching constraint. The reconfigurable floating impedance module is suitable for field programmable analog array. To verify the scheme a reconfigurable floating resistor and a reconfigurable floating capacitor are designed and simulated using PSPICE and the results thus obtained justify the theory.
