Studies on CMOS Digital-to-Analog Converters

January 1, 1970

SensorsThis 276 page thesis surveys D/A architectures, covering basic D/A conversion, behavioral modeling, current-steering D/A converters and oversampling D/A converters.


Design And Analysis Of MEMS Angular Rate Sensors

January 1, 1970

SensorsThis 81 page Master’s thesis from the Indian Institute of Science (2006) discusses different MEMS gyro designs (two for out-of-plane motion, and two for in-plane motion), damping mechanisms, equivalent lumped parameter models and simulated results.


Robust Micromachined Vibratory Gyroscopes

January 1, 1970

SensorsThis 257 page PhD Thesis does a nice job of explaining the theory of MEMS angular rate sensors (AKA gyroscopes). It provides a basic introduction to the Coriolis response, which forms the theoretical basis for vibratory gyroscopes. It discusses different types of suspension structures, damping effects, drive mechanisms, etc.

Theory and Design of Micromechanical Vibratory Gyroscopes

January 1, 1970

SensorsThis 20 page excerpt from The MEMS/NEMS Handbook provides a “general approach to the analysis of the dynamics and errors of different types of micromechanical vibratory gyroscopes as well as calculation of their performances for application in the design of such gyroscopes.”


System and Circuit Design for a Capacitive MEMS Gyroscope

January 1, 1970

SensorsThis 279 page PhD Thesis from the Helsinki University of Technology discusses 1 and 2 degree of freedom resonators, the Coriolis Effect, mechanical-thermal noise, and bulk and surface micromachining. It reviews a number of published microgyroscopes, discusses synchronous demodulation, resonator excitation, capacitive readout and more.


MEMS Accelerometers

January 1, 1970

SensorsThis is a nice, 17 page, introduction to MEMS accelerometers. It starts with a basic introduction to MEMS, moves on to capacitive plate sensing and demodulation, sensor noise characteristics, applications and MEMS fabrication.
