Abstract :
A new multi-mode multifunction filter using CDBA is proposed. The original filter has a single current input and three voltage outputs and operates in transimpedance-mode. It can generate all biquadratic filter functions of low-pass, high-pass and band-pass, and also band-reject and all-pass filter responses by selecting different output signal combinations. This filter can be converted into voltage-mode by an additional input resistor. It can also be used in current-mode at the output by using one extra load resistor at each output. With these additional resistors at the input and outputs the filter operates in transadmittance-mode. The structure of the new filter proposed contains two capacitors, three resistors and three CDBAs.
