[Ideas For Design]
Tiny smart card OS for PIC16C84
ISO7816-compliant “asynchronous” smart cards consist primarily of nonvolatile memory (ROM, EPROM, and/or EEPROM), managed by an embedded 8-bit microcontroller. Usually, this microcontroller derives from a very popular processor family such as the... — Contributing Author

Detector yields sensitivity with ultra-low power consumption
RF ID tags, circuits that detect a “wake-up” call and return a burst of data, must operate on a very low quiescent current for weeks or months, yet have enough battery power in reserve to answer an incoming call. If the system operates in the... — Contributing Author

[Ideas For Design]
Customize and improve an oscilloscope differential probe
Differential active probes for oscilloscopes allow measurement of small differential voltages while rejecting common-mode signals. Commercially available differential active probes can be dc- or accoupled. When ac-coupled, however, these probes have a... — Contributing Author
