Samprajani Rout's ISCAS 2017 paper among top papers of the conference
- Wednesday, 28 June 2017
ISCAS 2017 paper No. 1849, entitled “Structured Electronic Design of High-Pass ΣΔ Converters and Their Application to Cardiac Signal Acquisition” has been selected as one of the top contributions to the conference and an extended version of the paper has been invited for the TBioCAS Special Issue on ISCAS 2017. Authors of the paper are Samprajani Rout and Wouter Serdijn (Section Bioelectronics)
Abstract of the paper:
Achieving an accurate sub-Hz high-pass (HP) cutoff frequency and simultaneously a high accuracy of the transfer function is a challenge in the implementation of analog-to-digital converters for biomedical ExG signals. A structured electronic design approach based on state-space forms is proposed to develop HP modulators targeting high accuracy of the HP cutoff frequency and good linearity. Intermediate transfer functions are mathematically evaluated to compare the proposed HP Sigma-Delta topologies with respect to dynamic range. Finally, to illustrate the design method, an orthonormal HP Sigma-Delta modulator is designed to be implemented in 0.18 um technology which achieves a linearity of 12 bits.
Grant for the development of smart cathethers & implants
Ronald Dekker, Vasiliki Giagka, Paul de Wit, Wouter Serdijn and Lina Sarro received a grant concerning the development of smart catheters and implants. The project is financed by ECSEL Innovation actions, Call 2017.
Electrical Implants -- small devices with huge potential
Since the introduction of the pacemaker in 1958, much has changed in the world of electrical stimulation. Whereas the first electrical implants targeted muscles, the implants of today are flexible and focus mainly on the nerves in our body. The concept, however, remains unchanged: electrical implants give control back to the body. Vasiliki Giagka, Assistant Professor of Bioelectronics at TU Delft, talks about the past, present and future of her field of research.
