Synthesis of RC active filters using controlled sources

A technique is described for improving the sclecuvir.v of a low-sensitivity multi. loop negative feedback fictive network, which uses one operational amplifier. Voltage amplifiers with positive finite gain arc introduced inside the various loops of the network. This simplifies quite considerably the network function and improves the selecbivit.y for 11 given range of clement values ,vhilc not affecting the low sensitivity of t.he network. Also, additional low impedance out.put.a are available which for a particular input make the network suitable for the simultaneous realization of more than one function (with common poles but different zeros). Second and third-order networks are examined in detail and experimental results arc given from their usc in t.he realization of a band-pass and a low-pass filter.
