The Zen of Sensor Design

Contributed by Mike Stanley

Originally posted on Freescale’s Smart Mobile Devices Embedded Beat Blog

About two years ago, I joined the Freescale sensors team, which focuses on accelerometers, pressure sensors, and touch sensors.

Prior to that, I spent a number of years in the Freescale’s microcontroller solutions group, where I was an architect for several digital signal controller and microcontroller product families. One of the first things I learned when I moved into the sensors group was that certain “rules of the game” that relate to microcontroller design needed to be adapted when dealing with sensors. An example is package selection. With most microcontrollers, package selection is based upon number of functional and power pins required, PCB assembly processes targeted and (sometimes) thermal characteristics. Performance considerations are often secondary, if they exist at all. Sensors interact with the real world. Mechanical stresses introduced during both package assembly and PCB mounting can affect electrical performance of the device; often showing up as additional offset or variation of performance with temperature. Even the compound used for die attach has a demonstrable effect on sensor performance, and must be considered early in the design process. Continue reading

Is MEMS Design Holding Back MEMS Growth?

Via EDA company Cadence’s community blog: Bringing MEMS Design To The Mainstream.

The article states that some factors are needed for a greater use of MEMS as a component in systems–standard MEMS design flows, integration between MEMS and EDA software tools, standard MEMS foundry processes. Interesting stuff. What do you think, MEMSbloggers? Would this spark a “tiny revolution” in MEMS adoption?
