TO-OTA based current-mode biquad filters

چکیده
Abstract—In this paper, a general two-admittance current-mode circuit structure using triple-output OTA is explored to derive new second-order multi-function filters using OTAs with few extra current outputs and with/ without grounded capacitors. Biquads filters have been realized by using various admittances like OTA-simulated resistor, series and parallel OTA-C resonators in the proposed general structure. PSPICE simulation results are also given for the proposed circuits.

High-fequency Cmos Integrated Filters for Computer Hard Disk Drive and Wireless Communication Systems
Operational transconductance amplifier and capacitor (OTA-C) filters have outstood among different types of filter due to high frequency and low power capabilities in the main stream digital CMOS technology. They have been widely used in computer hard disk drive (HDD) and wireless communication transceivers. OTA-C filters based on cascade and passive ladder simulation are well-known. However, m...

This paper deals with RC active biquad working in the so-called current mode (CM). The design approach uses only three transconductors (OTA) with the minimum necessary number of outputs and with only three passive grounded elements. The proposed filter has simple circuit configuration providing all standard transfer functions such as high-pass (HP), band-pass (BP), low-pass (LP), band-reject (B...

This article introduces a circuit which can function both as a quadrature oscillator and as a universal biquad filter (lowpass, highpass, bandpass). When the circuit functions as a universal biquad filter, the quality factor and pole frequency can be tuned orthogonally via the input bias currents. When it functions as a quadrature oscillator, the oscillation condition and oscillation frequency ...
