Butterworth response circuits come in both low- and high-pass versions, as well as ideal, Sallen-Key, emitter follower and DC accurate variants. Many decades ago, I published a Design Idea about using equal value resistors and capacitors to ...
One of the first problems a capacitive-sensor analog designer must face is the low-frequency cutoff. Theoretically, you must fulfill just one simple requirement: a sufficiently large input resistance of the preamplifier's first stage. In ...
I like to think I write good code, and I’ve used C and C++ almost since their inception. I admit to incorporating more than one unwanted bug into C applications that were eliminated after sometimes tedious diagnostic sessions. Almost every ...
Fabio Pasolini, STMicroelectronics MEMS accelerometers have had a dramatic impact on cell phones, gaming consoles, and location-based devices. MEMS-based gyroscopes and geomagnetic sensors are about to take it to a whole new level. The MEMS ...
The current-generation prototype of ST's body-motion reconstruction suit demonstrates the optimal performance of the miniaturized iNEMO multi-sensor nodes attached on each arm, forearm, thigh, calf, and two on the back; additional nodes can be ...
