Chip Technology: UMC 130 nm
Area: 10.5 mm2

Description: This chip contains four innovative IPs which are implemented in fully QDI asynchronous circuits. The designs target ultra-low power applications such as wireless sensor nodes and IoT. Due to their asynchronous implementation, the designed IPs are very robust against the parameters changes, such as power supply levels, temperature, and process variability.

List of designed IPs:

- Optimized asynchronous AES crypto processor (2 versions one of them is in counter mode)
- Asynchronous implementation for Present: A light weight encryption for IoT and WSN.
- Asynchronous implementation for grain: An ultra-lightweight encryption for IoT and WSN.
- All digital test pattern generator based on self-timed rings.

Chip Technology: GF 65 nm (in collaboration with UAE)
Area: 12 mm2
Description: A body sensor network chip that contains power management blocks, energy harvesting blocks, medical data analysis blocks and asynchronous blocks.

DC-DC Converter: a hybrid converter for dynamic voltage scaling that is a mix between buck and switched capacitor converter. Measured results show an on-chip efficiency of 93% higher than anything reported in literature.

ERUST: A new microarchitecture level technique that reduces the power consumption. In this technique, we are using a modified razor architecture to make the circuit robust against error generation. When low power mode is activated, the supply voltage is reduced and the critical path generates error. The implemented architecture recovers the error by borrowing time slack from the successive pipeline stages. Measured results show that the pipeline can work correctly at the same frequency at much lower supply voltage.

Energy Harvesting: Including MPPT matching, self-starting blocks, mixer between light, thermal, and piezoelectric harvesters, and DC-DC converter.

Data communication blocks: Including asynchronous data communications core-core and off-chip.

Chip Technology: CMOS 180nm TSMC technology

Area: 4 mm2

Objective: Leukemia detection and characterization

Description: The chip consists of two main parts. 1) The electric field generator part, which is a quadrupole electrode configuration to produce the required electric field profile. 2) The sensing part, which is an array of the Differential Electric Field Sensitive Field Effect Transistor (DeFET).

Electric Field Generator part: The used electrodes are the quadrupole configuration; through which we can control the profile of the electric field by connecting the whole four electrodes, or some of them, to the inputs received from the LabVIEW via the DAQ.

Sensing Part: The sensing part is composed of an array of DeFET sensors. We can detect the electric field by using the Electric Field Sensitive Field Effect Transistor , as a novel electric field sensor. Figure 4 shows the schematic structure of the eFET. It consists of two adjacent drains, two adjacent floating gates with distance “Y” between them, and one source. For the eFET, it is equivalent to two identical enhancement MOSFET devices. Under the influence of the electric field, the current imbalances of the two drain currents occur. Due to the drain current dependence on the gate voltage, the eFET can sense the difference between the two gates voltage, which reflects the intensity of the applied electric field. To increase the measurement range of the eFET, we are using the CMOS concept to implement the Differential Electric Field Sensitive Field Effect Transistor (DeFET) sensor, and this sensor will be the basic sensing block in the sensing part of the proposed CMOS Biochip.

The neural interface chip area is 1.5 mm X 1.5 mm in 130 nm UMC CMOS technology. The chip is designed to be interfaced with deep brain stimulation electrodes of length 3 mm with 256 monitoring channels (64 channels on 4 shafts) and 16 stimulation channels. The chip contains the required analog conditioning circuits such as 256 Low Noise Amplifiers (LNAs), 256 filters, 256X1 analog multiplexer, and 12-bit Time-based Analog to Digital Converter (TADC). Moreover, it contains 16 stimulation channel for treatment that contains 8-bit Digital to Analog Converter (DAC), 1 X 16 analog demultiplexer, and 16 drivers. Following the analog conditioning circuits, there is a digital processing unit that is used to compress the data and make it read for transmission.

The chip is under fabrication with the support of the ITIDA funding agency, Egypt and the collaboration with Novela incorporation, Canada.

The low power FPGA chip area is 3.2 mm X 3.2 mm in UMC 130 nm CMOS technology. The chip is designed by implementing an embedded On-Chip Network (OCN) inside the FPGA chip to reduce the interconnect power and delay. This OCN is expected to increase the FPGA chip performance and reduce the routing complexity by providing kind of high ways inside the chip (OCN routers). The chip includes the FPGA fabric using 4-bit LUT, 3-LUTs cluster, 50% flexibility, and 24 bidirectional channels. It also includes 4 OCN routers with the required interface to talk to the fabric as well as the SRAM programmer required to configure the FPGA chip once fabricated.

The chip is under fabrication with the support of Fabrication Catalyst (FabCat), Egypt.

The tunable antenna for reconfigurable IoT RF transceivers is a 2 cm X 2 cm square micro strip antenna designed with reconfigurable side length and corner dimensions. The side length tunes the antenna frequency and the corner dimensions tune the antenna bandwidth. The reconfigurability is performed by using RF MEMS switches.

This chip is under fabrication, in collaboration with the British University in Egypt (BUE), Egypt, and University of Bristol, England, and with the support of ITIDA funding agency, Egypt.

The center has built low budget solar characterizer to be used in conjunction with our solar panel models. The current direction is to use this as a nucleus for power generation SCADA systems and the industrial design to use it as a measurement device in the market.

The inverter implements MPPT, highly efficient, is of easy maintenance and upgrades. The modality of the design makes the modification to support multiple power generation capacities very cheap. The prototype is now being industrially design for market penetration.
