Due to the globalization of the Integrated Circuit manufacturing industry and wide use of third party IP in the modern SoCs has opened the backdoor for Hardware Trojan insertion. The detection of Hardware Trojan is challenging because of its very rare activation mechanism and unpredictable change in the functionality of the system. This paper proposes a new hardware Trojan detection scheme using power...
In this paper, a novel design of diaphragm based pressure sensor has been proposed, which may find its application in Intra Uterine Pressure Catheter (IUPC) system. The novelty of the device lies in the fact that it has got patterned slots over the top layer of the diaphragm similar to a chess-board pattern. This sensor is then compared with a plane diaphragm of same dimensions. In same range of input...
Pressure microsensors are very frequently used for applications encompassing a wide range of operating pressure ranges. However, it is possible to use the same pressure sensor for different operating ranges (in a limited range) with satisfactory performance. In this work, we report the possibility of using a single sensor for different pressure ranges. Operating the sensor at a lower pressure range...
The paper presents the process design, simulation and characterization of a silicon-on-insulator (SOI)-based dual-gate metal oxide field-effect transistor (DG MOSFET) with Al metal gate. The proposed structure is an N-channel device, using aluminum nitride (AlN) as gate dielectric. The fully depleted SOI-based DG ISFET compatible with the complementary metal-oxide-semiconductor (CMOS) process is considered...
This paper reports the fabrication of n-type MOSFET using Si3N4 as dielectric on the same wafer as ISFET for ISFET characterization. The paper presents the fabrication, simulation and characterization of metal-oxide field-effect transistor (MOSFET). The gate of the ISFET is stacked with Si3N4 sensing membrane layer that has been deposited using LPCVD system to cover the gate area. Output and transfer...
This paper presents a 2.47 GHz capacitively transduced micromechanical disk resonator based on a Wine Glass mode of vibration. An ultra nano-crystalline diamond (UNCD) material has been used to achieve high frequency-quality factor (f.Q) product for RF applications, since this material provides highest young's modulus up to 1000 GPa and therefore highest acoustic velocity of 15000 m/s. Mode shape...
In this work, novel layouts of a 4:1 CMOS transmission gate multiplexer are presented. The proposed layouts are realized by following the design rules for 45 nm and 90 nm CMOS processes, with a supply voltage of 1.2 V. Both layouts are designed using two different routing strategies — using only one metal layer, and using two metal layers. The power dissipation and area are noted and compared in all...
