| Abstract: | This paper presents a novel current-mode (CM) second-order filtering configuration capable of realizing two filtering functions simultaneously. The circuit employs a single current differencing transconductance amplifier (CDTA), two capaci-tors and a resistor. The circuit can realize highpass (HP) and bandpass (BP) filtering responses simultaneously and bandpass (BP) and lowpass (LP) responses through RC:CR transformation. All active and passive sensitivities are low. PSPICE simu-lation results are included. |
