Title: An ultra low-power CMOS EMG amplifier with high efficiency in operation frequency per power
Author: Jaya, Gibran Limi; Chan, Pak Kwong
Copyright year: 2009
Abstract: A new ultra low-power CMOS Electromyograph (EMG) amplifier is presented in this paper. It is based on the application of a novel capacitive load reduction circuit technique to the capacitive-reset switched-capacitor circuit architecture. This is achieved by adding a capacitor in series with the capacitive load of the amplifier so as to reduce the total effective load capacitance being seen by the op-amp for reducing power driving requirement. The amplifier is designed using CSM 1.8V 0.18μm triple-well CMOS process technology and simulated using realistic BSIM3 models. The amplifier dissipates only 15.14μW at a dual power supply of ±0.9V. It has has a gain of 40dB at dc and 38.5dB at 3.2kHz. The estimated passband inputreferred noise is 2.08μVrms.
