| Summary: | A new multi-function high-order current-driven filter is proposed. The filter uses only
operational amplifiers, and operational transconductance amplifiers (OTAs). Without
using any external passive elements, a variety of high-order input-current/output-current
and/or input-current/output-voltage responses can be realised without changing the
circuit topology and without any matching or cancellation conditions. The parameters of
the high-order filter responses can be electronically tuned by adjusting the bias currents
of the OTAs. |
