Design Active Band Reject Filter Using Op-Amp and Operational Transconductance Amplifiers
Farouq M. Al-Taweel · 2013
Abstract: The article describes the usefulness of the operational transconductance amplifier as a voltage controllable current gain (VCCG), of the active band reject filter (BRF) and critical frequency for best design filter requirements using bipolar junction transistor (BJT) and OTAs to control the center frequency (f 0) and quality factor of the proposed Active Band reject filter (BRF).
