dc.description.abstract | This thesis presents an analytical approach to some key issues related to the design of
biopotential amplifiers for use in long-term ambulatory recording of the electrocardiogram
(ECG) employing pasteless or dry electrodes. The two principal problems of low-frequency
distortion and immunity to common-mode interfering signals are analysed in detail. There
is also an algorithm for the identification of the model parameters of a group of systems
simulated as a double-time-constant network in an attempt to characterise the interface
composed of the skin and the sensing electrodes. In the case of low-frequency distortion, new
input impedance specifications for dry-electrode electrocardiography are derived from the
analysis of performance requirements issued in international standards and recommendations.
This is necessary if the low-frequency components in the ECG that contain valuable clinical
information about the condition of the cardiovascular system are to be faithfully reproduced.
The factors defining the ability of the recording system to effectively reject external unwanted
voltages are then determined to allow the suitability of a small number of amplifier circuit
configurations to be assessed. The design of new instrumentation amplifiers is finally outlined
and their performance evaluated in a worst-case scenario. | |
