Design of an Implantable Neural Interface

Type: Applied Research

Areas: Microelectronics, instrumentation, Biomedical Engineering.

Begin: January/2015

Participants: UFSM, UCBM (Rome, IT.)

Funding: MCT, CNPq

Abstract: Design and testing of a wireless implantable system for both acquiring and applying signals from/into peripheral nerves. The system comprehends: implanted and external blocks for: signal conditioning, data conversion, stimulator, control, energy, and communication.

Design Tools: Virtuoso, Innovus, Spectre, Allegro/OrCad.


Design of an Analog to Digital Sigma Delta Converters for programmable base-band using Switched Current techniques

Type: Applied Research

Areas: Microelectronics, Analog, and Mixed Signals

Begin: Mar/2009

Participants: UFSM/Gmicro/PPGEE


Abstract: This project aims to design an ADC Sigma Delta type, which meets the standards GSM / WCDMA / WLAN capable of being managed in accordance with the required operating bandwidth. The approach of constructing circuits will be using the technique of switching current (SI). The technology to be used preferably will be available in the manufacturing process CEITEC.
