OTA based Current Mode First Order and Second Order Amplitude Equaliser
This paper presents OTA (operational transconductance amplifier) based current-mode first order and second order amplitude equalizer circuits. The advantage of these circuits are simple architecture, use of grounded capacitor and low sensitivity values. The proposed OTA-C amplitude equalizer circuits are verified using PSPICE simulator.
