The second order LP filtering structures using the CCC

Abstract

Frequency filtration of electric analogue signals is a question that bothered engineers for many years. The filtered signal is mostly a voltage signal, however, it is of-ten necessary to design the structure for which parameters of transmission of other electric signals such as current are important. Very fast developing techniques of digital systems did not eliminate, as was thought, the need of the use of analogue systems, but only imposes on them very high requirements. Authors have proposed in this paper a new biquad low pass filtering structures with Controlled Current Conveyors.
