April 2015 edition – Vol.7 no.4

2014 annual report and general assembly of members
Our latest annual report is now available (2014 annual report). Also, we remind all members of ReSMiQ that our next general assembly will be held on May 7, 2015 at Polytechnique Montréal. We will present the annual report of our activities and elect the members of the executive committee as well as the board of directors for 2015-2016. The attending members will vote on the Director’s election for the next term.

Financial support of our strategic cluster
The management team of ReSMiQ is expecting the decision of the Fonds de recherche du Québec – Nature et technologies (FRQNT) pertaining to the grant renewal application for our strategic cluster which should be announced very soon. After sending the letter of intent in May 2014 and a full application in October, we met with the visiting committee last January. The center’s management would like to thank everyone who contributed in the growth of ReSMiQ and provided a considerable effort in the production of this application. Also, we take the opportunity of the results of the latest NSERC discovery grant program to congratulate all our members who have just renewed their grant this year and particularly all applicants who saw a significant increase.

The 13th edition of NEWCAS will be held in Grenoble on June 7 to 10. The call for papers has generated a record number of 326 articles submissions. We encourage all our members to participate in the next edition. ReSMiQ will, as for every edition, provide a valuable financial assistance.

4th edition of the ReSMiQ Innovation day (RID2015)
The 4th edition of the ReSMiQ Innovation Day (RID) will be held on October 15, 2015. This competition is open to all full-time students enrolled in a university or a college/CEGEP in the province of Québec. The call for project has been sent out and all students interested in showing their research can submit it until May 4, 2015. We are counting on all members to encourage their students to participate and circulate this announcement among their colleagues in connected fields.

A Configurable Multi-Rail Power and I/O Pad Applied to Wafer-Scale Systems

A novel platform for rapidly prototyping, the WaferBoard, is being developed in our lab to accelerate the time to market of microelectronic systems of increasingly complexity. This platform is based on an active surface implemented using a 200 mm full wafer device. This active surface is covered with over 1.2 million tiny conductive pads called NanoPads interconnected with a configurable interconnection networks. Every Unit-Cell comprises a 4 × 4 array of NanoPads, and a 32×32 array of Unit-Cells defines a reticle image. The assembly at wafer-scale level is called WaferIC and is achieved by photo-repeating 76 copies of the reticle image that are stitched together to implement wafer scale interconnections (Fig. 1). We propose in this paper a novel configurable multi-power-rail pad that combines power supply support circuits and a digital input/output (I/O) buffers designed for a wafer-scale system. This wafer-scale platform includes a reconfigurable wafer-scale circuit, the WaferIC, comprising an alignment-insensitive surface that can be configured to interconnect any digital components manually deposited on its surface. The proposed multi-power-rail pad minimizes power losses and heat dissipation within the circuit. The pad that is fed from two distinct voltage sources providing power at 1.8 and 3.3 V has been implemented and tested. This pad has two merged configurable control loops that can select the power source. Merging takes place through shared transistors. This dual supply pad embeds a voltage regulator that achieves a fast response time of 21.1 ns and that can operate over a wide range of configurable regulated output voltage, from 500 mV up to 2.955V. This regulator is capable of providing a maximum output current of 40 mA while needing only a very small quiescent current of 126 μA. The regulator's power supply noise rejection ranges from -25 down to -40 dB for frequencies ranging from 1 kHz up to 1 MHz. The embedded digital I/O pad shares a common output with the power distribution and can be configured from 0.5 up to 3.3 V for a maximum speed of 250 MHz.
