A Low-Power Low-Noise Instrumentation Amplifier for Wearable Applications

This paper presents the design and evaluation of two low-power and low-noise operational transconductance amplifiers (OTA) topologies for wearable applications. Current-Mirror OTA and Folded-Cascode OTA are designed using gm/ID method for optimal sizing focusing on low-power design in order to meet the specifications needed for wearable applications. Simulation results and comparative discussion are presented for the two topologies designed on a 0.5 /µm CMOS process.
