This book provides an invaluable reference to Piezoelectric Accelerometers with Integral Electronics (IEPE). It describes the design and performance parameters of IEPE accelerometers and their key elements, PE transducers and FET-input amplifiers. Coverage includes recently designed, low-noise and high temperature IEPE accelerometers. Readers will benefit from the detailed noise analysis of the IEPE accelerometer, which enables estimation of its noise floor and noise limits. Other topics useful for designers of low-noise, high temperature silicon-based electronics include noise analysis of FET amplifiers, experimental investigation and comparison of low-frequency noise in different JFETs and MOSFETs, and ultra-low-noise JFETs (at level of 0.6 nV/Hz). The discussion also includes ultra-low-noise (at level of 3 ng/Hz) seismic IEPE accelerometers and high temperature (up to 175 C) triaxial and single axis miniature IEPE accelerometers, along with key factors for their design. - Provides a comprehensive reference to the design and performance of IEPE accelerometers, including low-noise and high temperature IEPE sensors; - Includes noise analysis of the IEPE accelerometer, which enables estimation of the its noise floor and noise limits; - Describes recently design of ultra-low-noise (at level of 3 ng/Hz) IEPE seismic accelerometers and high temperature (up to 175 C) triaxial and single axis miniature IEPE accelerometers; - Compares low-frequency noise in different JFETs and MOSFETs including measurement results of ultra-low-noise (at level of 0.6 nV/Hz) JFET; - Presents key factors for design of low-noise and high temperature IEPE accelerometer and their electronics.

High performance, micro-g resolution, small size, low cost, low power accelerometers are needed in many applications such as inertial navigation, Unmanned Aerial Vehicles (UAVs), and GPS augmentation. Several sensing methods have been used, including piezoresistive/electric, resonant, tunneling, and capacitive techniques. Capacitive sensing has several advantages in terms of high sensitivity, stable DC-characteristics, low power dissipation, low temperature sensitivity, and low noise floor. This research work demonstrates full functionality of high- sensitivity, low-noise capacitive multi-axis accelerometers. In order to achieve micro-g resolution, two different structures have been utilized: a Silicon-On-Glass (SOG) accelerometer, and an all-silicon accelerometer. A monolithic fabrication technique for Post-CMOS MEMS is also developed. Finally, a 3-axis single-chip accelerometer is presented. The 3-axis accelerometer shows 3pF/g sensitivity and sub- g/rtHz mechanical noise floor. The 3-axis accelerometer with the readout circuit provides noise floor of 1.6 g/rtHz and 1.1 g/rtHz for in-plane and out-of- plane devices, respectively.

Strong dependence of surface plasmon resonance (SPR) on coupling parameters offers new varieties of sensing mechanisms in nano and micro-scale engineering fields. In this study, design, fabrication and characterization of MEMS displacement sensors that utilize angular dependence of grating coupled SPR condition are explored. Several surface plasmon polariton (SPP) excitation mechanisms are reported in the academic literature. One of them which is quite adaptable to microelectromechanical systems is grating coupling scheme. In this scheme, thin metallized grating structures are particularly designed depending on the desired wavelength and the angle of incidence of the SPP excitation light. Various lithographic techniques (nanoimprint, electron beam and optical lithography) are used to nanofabricate those certainly defined gratings. MEMS displacement sensor designs relying on the principle of angular displacement detection scheme are developed. In addition, a MEMS accelerometer design with plasmonic readout with nano-G noise floor is presented. Novel arrayed sensors combining the sensitivities of plasmon resonance and micromembrane type sensors may provide unprecedented performance.

Micro Electro Mechanical Systems (MEMS) have an extensive use in different areas of technology. Inertial sensors (accelerometers and gyroscopes) are one of the most widely used devices fabricated using MEMS technology. MEMS accelerometers play an important role in different application areas such as automotive, inertial navigation, guidance, industry, space applications etc. because of low cost, small size, low power, and high reliability. This book presents a detailed SIMULINK model for a conventional capacitive sigma-delta accelerometer system consisting of a MEMS accelerometer, closed-loop readout electronics, and signal processing units (e.g. decimation filters). By using this model, it is possible to estimate the performance of the full accelerometer system including individual noise components, operation range, open loop sensitivity, scale factor, etc. The developed model has been verified through test results using a capacitive MEMS accelerometer, full-custom designed readout electronics, and signal processing unit implemented on a FPGA.

Sensors and devices, based on micromachining technology, known as micro-electro-mechanicalsystems or MEMS, have been received increasing attention so far in recent years. Micromachined inertial sensors, consisting of accelerometers and gyroscopes, are one of the most important types of silicon-based sensor. MEMS capacitive accelerometers have been extensively used in automobiles, inertial navigation systems, earth quake detection and many other bio-medical applications. This book deals with the design of a monolithic 3DOF MEMS capacitive accelerometer using both analytical and numerical techniques. Monolithic accelerometer is a single structure having three individual single axis Accelerometers on a single substrate and utilizes a surface micromachining technology using standard PolyMUMPs process. The designed accelerometer is 3mm×3.1mm in size, has low mechanical noise floor, high sense capacitance and high sensitivity along in-plane (x and y) and out-of-plane (z) axes. Performing a detailed finite element analysis in ANSYS 11.o, physical level simulation has been done to verify the deflection for x, y and z axes with respect to the applied acceleration (g).
