Communication protocols: For a wireless ECG solution

This report is part of the WiECG project. The goal of the WiECG project is to create a prototype device that makes it possible to perform a 12-lead ECG on patients without wires from a patient to the monitor. The solution consists of a transmitter and receiver of which one is close or on the patients body and the other is connected to a monitor....

Structured Electronic Design of High-Pass ∆Σ Converters: And their application to cardiac signal acquisition

With the bandwidth of the ECG signal extending from sub-Hz to 200 Hz, a major challenge for an ECG readout system lies in implementing the high-pass (HP) cut-off frequency as this translates into the realization of large time constants on-chip.Although techniques such as those based on the use of pseudo-resistors to obtain very large time...

A 0.6V, 1μW, low-power low-noise instrumentation amplifier for ECG/BioZ measurement in 40nm CMOS

This thesis presents a low-power low-noise instrumentation amplifier designed to be implemented in 40 nm CMOS technology and operating from a 0.6 V supply, intended for use in electrocardiogram (ECG) and bio-impedance (BioZ) signal acquisition. This instrumentation amplifier has one ECG channel, one BioZ channel and allows both signals to be...

Fully Integrated Analog Front-end for a 2-electrode ECG device

Cardiovascular diseases are leading cause of deaths worldwide. With increasing graying population and limited health infrastructure there is a need for portable and implantable ECG devices to diagnose these diseases early on. In general an ECG device requires three or more electrodes, which need to be applied to the body via a gel, to obtain a...
