Circuits for intrachip communications and networks-on-chip
Using full-rail interfaces on chip (in which CMOS inverters drive CMOS over RC-dominated interconnect) is a very energy inefficient means of communication (for a given amount of bandwidth density) and results in unnecessarily long wire latencies. We have been developing techniques to take full advantage of the transmission line properties of on-chip wires to achieve […]
Measurement and modelling of variability in nanometer-scale CMOS
Process variability is a critical concern in nanometer-scale CMOS, owing to random device fluctuations (dopant fluctuation, line-edge roughness) and also reticle and proximity effects, which have difficult-to-predict impacts on device characteristics. Traditionally, process variability is characterized by one of two methods: either individual devices with pads are characterized on an automated wafer stepper or a […]
CMOS fluorescence-based active microarrays
This project is a multidisciplinary effort to novelly exploit CMOS silicon microelectronics in the design of low-cost, portable, self-contained “gene chip” technology for nucleic acid measurement and detection. Much of this effort is focussed on developing active substrates based on fluorescence detection. One such active microarray is shown below, capable of time-resolved fluorescence detection for […]
Fluorescence Lifetime Imagers
Fluorescence lifetime based imaging systems have historically been limited by long acquisition times (on the order of seconds). Integration of FLIM systems onto CMOS provides the potential to increase acquisition speed an pave the way for new applications.
