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. |
