Low Power CMOS Folded Electro Cascode Amplifier Design for Electrocardiogram Applications

This paper presents the designing of folded electro cascode amplifier which is mainly used in electrocardiogram (ECG) applications. The ECG front end amplifier which is used nowadays are sensitive to noisy environments which can vary the signal produced. The proposed amplifier which is highly stable in noisy environments because of using electro cascode stage is used in the proposed amplifier. It consumes low power and low voltage which can enhance the better performance and also low noise. The amplifier is designed to operate in 1.2 V. The design is implemented in 45 nm CMOS technology and the layout design has been designed in cadence virtuoso software. The simulation results shows that the amplifier is suitable for low power applications and can be used for wearable devices.
