Abstract

This paper proposes a method that analog multiplier and current feedback operational amplifier have been used to form second-order voltage-controlled multifunctional filter. The designed circuit has been achieved theoretical analysis, PSPICE simulation and actual measurement. It can simultaneously realize low-pass, high pass and band pass filter function. Results show that the pass band can be adjusted with the frequency range of the input signal, and can be used in the field of frequency characteristic analysis, harmonic analysis, frequency measurement, signal detection. Furthermore, it shows more importance in theoretical significance and application prospects.
