Make Your Next Design As Solid As A Rock

January 1, 1970

SensorsIf you need a quick introduction to crystal oscillators, this article is for you. Four pages of text and figures introduce you to the topic and discuss oscillator options and specifications you should know about.


BTC M850 Optical Mouse Teardown

January 1, 1970

SensorsAt EEHP, we both do and read product teardowns for their educational value. This report looks at the inner workings of an optical mouse, providing both theory and implementation details.


Control of Stepping Motors – A Tutorial

January 1, 1970

SensorsThis web-based tutorial on stepper motor control has hidden depths you won’t notice when opening the page. But take the time to click on the links in the “Index”, and you will find a nicely illustrated set of tutorials done from a practicioner’s perspective.


The Design of Band-Gap Reference Circuits: Trials and Tribulations

January 1, 1970

SensorsThis brief article by Bob Pease gives a quick introduction to band-gap circuits, and progresses to discuss layout problems, startup problems, oscillation issues, voltage errors and modeling problems.


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.”
