In this paper, a new multi-terminal active component, namely current backward
transconductance amplifier (CBTA) is proposed. The design procedure for the systematic
realization of current-mode ladder filters using proposed active component is also
presented. In order to demonstrate that the CBTA considerably simplifies the leapfrog
structure of the current-mode ladder filters, a fifth-order Butterworth low-pass filter that
requires a minimum of active components is presented. The theoretical results are …
