PWM BASED LOCK-IN BIOIMPEDANCE MEASUREMENT UNIT FOR IMPLANTABLE MEDICAL DEVICES
Aivo Kuhlberg, Raul Land, Mart Min, Toomas Parve
Abstract:
A method for design of the switching mode lock-in bioimpedance measurement unit is proposed. The unit is foreseen to use in implantable medical devices for making medical experiments in vivo. The solution is aimed to lessen the errors caused due to sensitivity of the switching mode lock-in signal converters to the odd higher harmonics of an input signal. The applied method is similar to pulse width modulation (PWM), and it is oriented to achieve minimal complexity and low energy consumption.
