A new topology of shadow bandpass filters is presented in this paper. The proposed circuit employs the active building block of three voltage differencing transconductance amplifiers (VDTA) along with two grounded capacitors. This results in an additional attractive feature of being fully active and minimal component-count. Practical realization of the VDTA is also given and employed for circuit verification. PSPICE simulation with model parameters of 0.18μm CMOS technology is included to confirm the filter functionality of the proposed filter.
