| Summary: | This article presents a configuration that can simulate both a resistor in
series with a frequency-dependent negative-resistance (R-D) and a resistor
in series with a capacitor (R-C), with a different selection of passive
elements. The proposed circuit employs only two
current-controlled-current-feedback- amplifiers (CC-CFAs) and grounded
passive elements. This configuration does not require passive element
matching, and the simulated equivalent element values can be tuned
electronically by applying a biasing current to the CC-CFAs. To demonstrate
the application of the proposed grounded series R-D impedance simulator, it
is applied to a second-order notch filter and a fifth-order elliptic lowpass
filter, whereas the series R-C impedance simulator is applied to a
secondorder resonance circuit to find the band-pass response of the input
current. Our theoretical analysis is confirmed by the results of a PSPICE
simulation. |
