Role

The nano and microelectronics group of CTS-UNINOVA has the task of designing and testing a highly flexible and multifunctional adaptive deep-submicron System on Chip (SoC). The latter will have the capability to: interface with the monolithic, microfluidic sensing chip of carbon-nanotubes-based resistive chemical sensors, of MEMS physical and rheological resistive sensors, interface with the energy harvesting sub-system, integrate a digital processing unit (e.g., microcontroller and memory), which will support advanced power consumption management strategy and smart/cognitive high level algorithms, integrate a short-range wireless data communication bidirectional link.

To accomplish this task the CTS-UNINOVA will employ its expertise on designing analog, digital and mixed-mode microelectronics circuits under deep-submicron CMOS technology (130 nm and below), namely, programmable switched-capacitor filters, low-power Sigma-Delta ADC, RF receivers, among others.

Expectations

The expected outcomes relates to the objective of implementing a highly power efficient SoC capable of operating at a low voltage supply voltage (1 V or lower). Contributing to this is the designing of an innovative and linear analog matrix for routing the multi sensor generated signals to the low power analog processing units, namely, passive and adaptive sigma-delta converters.

Additionally it is intended to produce an efficient power management, by using a fully integrated capacitor based Maximum Power Point Tracking (MPPT) unit, to better use the energy collected by the harvester.
