A biasing based current mode analog front-end for biomedical applications

Abstract Electrocardiograms, Electromyogram, and Electroencephalogram, are very few extensions and low frequencies electronic detection system. An important part of their biomedical detection electronic system is the biopatensive props-device. In this article, analog front-end in a current mode has been proposed to bioptational signal acquisitions. It includes programmable profit-current (PGC) mode amplifier (MA) and 2nd current mode low-pass filter (CM-LPF). Amplifier operated and low-pass filter externally used ELIN circuits. EIN blocks were executed by the use of log-domain circuits. In the proposed circuit, a combination of pull up and pull down transistors which acts as an inverter is used for biasing purpose. The biasing is done in such a way that the transistors switch their region of operation between cutoff region and saturation region in order to perform switching action. The proposed current mode analog front-end consumes less material to implement circuit design.
