Synthesis of New Biquad Filters Using Two CFOAs
MetadataShow full item record
This paper deals with synthesis based on new autonomous circuit using two current feedback operational amplifiers. Four possible second-order structures are derived and several active RC filters are described. One new circuit of the band-pass filter is introduced in detail. Its parameters are studied symbolically, tested by simulations and confirmed by measurements.
