Abstract Modifications directly to a transistor’s source/drain and polysilicon gate through the backside of a SOI device were made. Contact resistance data was obtained by creating contacts through the buried oxide layer of a manufactured test structure. A ring oscillator circuit was modified and the shift in oscillator frequency was measured. Finally, cross section images of the FIB created contacts were presented in the paper to illustrate the entire process.

Tire pressure monitoring device/system (TPMS) is an electronic device that monitors the air strain of an vehicle tire and indicates the pressure to the driver.Upkeep of tire strain in automobile is vital owing to the reality depletion within the strain of tire ends up in diminished combustible potency and future scratch in tires which ends up in substitution of tires fairly again and again. In this paper the used conception relies upon eliminating above problems and observing those facts continuously using pressure sensor with the help of some devices and wireless modules such as zigbee or rf-transreciever and also STM32 on-chip computer. A different mouth is distended other than conventional muzzle within that device is found which communicate via wireless apparatus and obtained with the help of the wireless module such as zigbee gift out of doors and also the signal is been dispatched to on-chip computer which computer screen units and unveil the strain name (name of tire) and actual strain on a screen monitor which notify the person to fill the air in tire. With the use of this system the user of the vehicle can eliminate the wheel is alignment and supply protection to the vehicle.

This article focuses on a proposed Switched-Capacitor Dual-Slope based CDC. Special attention is paid to the measurement setup using a real pressure sensor. Performance scaling potential as well as dead zones are pointed out and discussed. In depth knowledge of the physical sensor behavior is key to design an optimal readout circuit. While this is true for high-end applications, low-performance IoT (Internet of Things) sensors aim at moderate resolution with very low power consumption. This article also provides insights into basic MEMS (Micro-Electro-Mechanical-System) physics. Based on that, an ambient air pressure sensor model for SPICE (Simulation-Program-with-Integrated-Circuit-Emphasis) circuit simulators is presented. The converter concept was proven on silicon in a 0.13 μ m process using both a real pressure sensor and an on-chip dummy MEMS bridge. A 3.2-ms measurement results in 13-bit resolution while consuming 35 μ A from a 1.5-V supply occupying 0.148 mm2. A state-of-the-art comparison identifies potential room for improvements towards hybrid solutions, which is proposed in subsequent publications already.
