Two grounded capacitance multipliers employing the current differencing transconductance amplifier (CDTA) are proposed. They can be easily modified to the floating versions by using an additional difference voltage amplifier. Each multiplier contains one CDTA, one capacitor, pseudo-grounded via a low-impedance CDTA input terminal, and one or two resistors. A careful error analysis is made and both circuits are compared in terms of their benefits and drawbacks. The results of the measurements on the specimens exploiting on-chip CDTAs correspond to the design objectives.
