Abstract
A new configuration for realization of current-mode notch and allpass filters is presented. It can synthesize second-order notch and allpass filters using a single current difference (Norton) amplifier and at most eight passive RC one port elements. Experimental results obtained from a notch filter realization are presented.
Highlights
At present, there is a growing interest in designing current-mode signal processing circuits
In many industrial electronic control systems, circuits are designed to operate off only a single power supply voltage
The current conveyor is typically designed for split power supplies and, current-mode active filters employing conventional current conveyors cannot be used in many industrial control applications
Summary
There is a growing interest in designing current-mode signal processing circuits In these circuits, the current rather than the voltage is used as the active variable either throughout the whole circuit or only in certain critical areas. The current conveyor is typically designed for split power supplies and, current-mode active filters employing conventional current conveyors cannot be used in many industrial control applications. The current difference amplifier, designed to operate from a single power supply, is a strong candidate for such applications. A literature survey, [see, for example, [3]-[5] and the references cited therein] reveals that while the current-difference amplifier has been extensively used in designing voltage-mode biquadratic transfer functions, no attempt has been reported yet for its use in designing current-mode biquadratic filter circuits
