Ultra-Low Power, Nw Level Bandgap Voltage Reference (Bgref)
With advances in the Internet of Things (IoT) applications and the expansion of mobile devices, energy consumption has become a primary focus of attention in integrated circuit design. These mobile battery-operated devices need to operate for extended periods without recharging and therefore requiring ultra-low energy consumption. Many IoT devices require operation in a wide range…
Read MoreCutting-edge, Physical Unclonable Functions Related to Inverter Trip Points
The Problem The huge amount of sensing devices found in future cars, homes, workplaces, and cities require a much stricter security requirement for identification and authentication. It is essential that during hardware communication, the two parties are capable of identifying each other through secret keys and reliable authentication protocols. A technique which has recently emerged…

The Problem The huge amount of sensing devices found in future cars, homes, workplaces, and cities require a much stricter security requirement for identification and authentication. However, when the variation is small, the logical value will be determined by noise and can vary from run to run and the bit is unstable. The unstable bits…
Read MoreInnovative Ultra-Miniature Ring Oscillator Temperature Sensor
The Problem An important power management functions in commercial IC’s is temperature sensing. Since commercial processors can have as many as 40 sensors, the industry is constantly pursuing a small, low-power sensor. The Solution We present a promising, novel ultra-miniature ring-oscillator sensor which at 750 um2 is the world’s smallest integrated smart sensor and has the…

The Problem The localization precision which is limited by the square root of N is obtained due to non-coherent addition of the collected photons. An increase in the precision is required as it leads to significant increase in the imaging resolution for the same amount of illumination of alternatively it allows the same resolution as…
Read MoreUltra-sensitive, Miniature, Low Power, Inexpensive Magnetometer
The Problem Currently, available inexpensive and miniature commercial magnetic sensors exhibit field resolution of hundreds of picotesla and above, while commercial sensors with field resolution of few picotesla and below are normally much larger and more expensive and in some cases operate only at cryogenic temperatures. Namely, there are no commercial magnetic sensors which are…

The Problem Color generation is commonly pigmentation related, and its pixel size is limited to a few and up to tens of microns, two orders of magnitude larger than the diffraction limit in the visible range. Colors can also be generated via interference processes in photonic crystals and in plasmonic sub-wavelength structures. Plasmonic color generators…

The Problem At the current rate of global energy demands, new, alternative energy technologies must be developed to accommodate our needs. For more than a decade, it was strongly believed that hydrogen can help address the growing demand for energy and slow down global climate change. Hydrogen fuel is used together with oxygen in an…
