Abstract [en]

In this work we provide measurements on low power envelope detector and compare them with results predicted by theory. This envelope detector is supposed to be used as a part of low power Wake-up radio for RFID applications. In the work we were mostly interested in noise parameters and blocker effect verification.

The detector we use is based on CMOS transistors biased in subthreshold region. It gives us low power consumption and high sensitivity. For power consumption about 10 uA and signal to noise ratio equals to 10, the achieved sensitivity is 1.8 mV.

The results of the work can be used to build low power envelope detector for specific requirements.
