Patch Clamp Amplifiers     |
|
We are the first group to fully integrate a
patch clamp measurement system for whole-cell
recordings in a millimeter size. This device is used
to study the physiology of living cells and to test and improve
the safety of medical compounds. The device enables
high-throughput patch clamp systems to test 384 wells
simultaneously. |

NeuroView     |
|
We have developed an implantable
optical neural recording interface to detect fluorescent
signals from voltage sensitive dyes and other
fluorescent probes. This device can be used in-vivo to
monitor networks of neurons in the cortex in real time
and with better than millisecond resolution. |

UWB Communication Circuits     |
|
We have developed a RF front end for an
UWB transmitter that can operate with sub milli-watt
of power at multi megabit rates and at micro watts of
power for kilohertz data rates. This device can be used
for body area networks and sensor networks. The device
uses the SOS process to optimize its operation at
high-speeds and low-power consumption. |

Neural Recording Amplifiers     |
|
We have developed a multi-channel
pulse based amplifier and data Converter for
bio potentials. The circuit can be used to record
neural activity, EEG, ECG signals, and field
potentials. The core of the circuit is a low-power
low-noise AC amplifier with an asynchronous delta
A/D converter. |

Visual Processing Hardware     |
|
We are developing bio-inspired neuromorphic
algorithms and neural processing hardware to model the
ventral pathways of the mammalian visual system. Our
model can implement fast categorization of hundreds of
objects in real time, bottom-up and top-down attention,
target selection, and saliency. |

Synthetic Retinas and Sensors     |
|
We develop neuromorphic event-based image
sensors that can extract relevant information from the
scene, and are inspired by the pre-processing,
compression, normalization and data reduction of the
human retina. Our recent image sensor prototypes find
applications in assisted living, security networks, smart
imaging, and video networks for Wireless Sensor Networks. |

Dataflow Computing     |
|
We are developing a dataflow computer aimed at speeding
up the computations of bio-inspired visual models. Our
approach is to provide a general-purpose system that can
be programmed like a standard PC. Our system is based on
a streaming micro-controller and a runtime reconfigurable
2D grid of computing elements. |

Photodetectors and Image Sensors     |
|
We are the first to design and test fully
functional image sensors arrays in the SOS process. We
have designed and tested PN photodiodes, PIN photodiodes
and MOS phototransistors. We have developed a CMOS UV
detector array capable of multiple 1000 fps in the SOS
process. |

Analog to Digital Converters     |
|
We have developed ultra-low power analog
to digital converters that take advantage of the
insulating substrate of SOS and deliver performance
comparable to deep sub-micron processes. We use
capacitors arrays that can only be fabricated in SOS/SOI
substrates. |

Energy Harvesting     |
|
We have developed ultra-low voltage
circuits in SOS that can extract energy from harvesting
sources. We can operate band-gap references, temperature
sensors, RF pulse modulators and voltage-controlled
oscillators and rectifiers with a 0.5V supply and
micro watt power consumption. |

3D Integration     |
|
We developed isolation techniques in Silicon
on Sapphire that are able to exchange power and data
between two parts of a die or two different dies. We use
this technology for assembling multi-chip modules that
are integrated in 3D. This research focuses on the design
and fabrication of a fully three-dimensional image sensor
and other prototypes of 3D integrated circuits. |
