Abstract
A current-mode high-order filter configuration is introduced using mul tiple current output operational transconductance amplifiers (OTAs). T he circuit has been constructed by employing a current-mode integrator and a proportional block as basic building units. It is shown that th e proposed circuit can realize a general class of high-order transfer functions. As an example, a fourth-order filter is given, together wit h simulated results by PSpice.
