Abstract

This paper presents the operational transconductance amplifier and capacitor (OTA-C) current-mode filter structures using DO-OTA with dual current outputs I_o and I_o/n (n>l) for low frequency applications which can be used to design for desired pole-Q without sacrificing the gain. Larger time constants are shown to be achieved by scaling feedback current(s) but without using components in the feedback network. The filter structures offer independent tunabilty of pole-Q. The use of these filter structures for low frequency applications is verified using TINA-TI circuit simulator.
