In this paper, the design and implementation of an RFID-like temperature datalogger prototype, based on ISO11784/11785 standard is presented. It was designed to communicate through an inductive coupling with a 134.2 kHz ISO compliant reader, similar to those regularly employed for livestock traceability. It uses a low power — low cost microcontroller(More)
Amplifiers for biological signals aimed to implantable medical devices require high gain and low noise, while maintaining very low power consumption. Therefore, a major challenge is the design of efficient low-noise circuits. These amplifiers work at low frequency ranging from sub-Hz to few kHz, thus besides the presence of thermal (white) noise, flicker(More)
