biquad filter has been presented. The proposed configu-
ration employs single VD-DIBA with minimum number
of passive elements, namely two capacitors and only one
resistor. The presented biquad can yield second-order
low pass, high pass, band pass, notch and all pass filter
responses without altering the circuit topology. The pas-
sive and active sensitivities are low. Simulation results
using 0.35 µm MIETEC technology have been presented
which prove the feasibility of the proposed new biquad
filter.
