EMI-Resilient Amplifier Circuits

by Marcel J. van der Horst, Wouter A. Serdijn, and Andre C. Linnenbank

Published 6 August 2013

This book enables circuit designers to reduce the errors introduced by the fundamental limitations (noise, bandwith, and signal power) and electromagnetic interference (EMI) in negative-feedback amplifiers. The authors describe a systematic design approach for application specific negative-feedback amplifiers, with specified signal-to-error ratio (SER). This approach enables designers to calculate noise, bandwidth, EMI, and the required bias parameters of the transistors used in application specific amplifiers in order to meet the SER requirements.

Ultra Low-Power Biomedical Signal Processing

by Sandro Augusto Pavlik Haddad and Wouter A. Serdijn

Published 1 January 2009

Often WT systems employ the discrete wavelet transform, implemented on a digital signal processor. However, in ultra low-power applications such as biomedical implantable devices, it is not suitable to implement the WT by means of digital circuitry due to the relatively high power consumption associated with the required A/D converter. Low-power analog realization of the wavelet transform enables its application in vivo, e.g. in pacemakers, where the wavelet transform provides a means to extremely reliable cardiac signal detection.

In Ultra Low-Power Biomedical Signal Processing we present a novel method for implementing signal processing based on WT in an analog way. The methodology presented focuses on the development of ultra low-power analog integrated circuits that implement the required signal processing, taking into account the limitations imposed by an implantable device.
