1. A universal radio frequency identification sensing system comprising:
- an integrated circuit having a single die including a clock as a clock generator, an analog front end as a transceiver, a digital control unit coupled to said clock and said analog front end, a memory unit coupled to said digital control unit, and a power management configured to distribute power; and
said single die further including a digital to analog converter with digital inputs coupled to the outputs of said digital control unit, and an analog output of said digital to analog converter coupled to a comparator first analog input; and
said single die further including a comparator output coupled to the input of said digital control unit, and a comparator second analog input configured to receive an analog measuring device or sensor module output.

Abstract
An embodiment including a radio frequency identification system/RFID transponder or tag, and the interface must be able to receive measuring signals from the analog measuring device(s) or sensor module(s). The radio frequency identification device and the interface are integrated as a single die. This single die is configured to not only transmit typical RFID signals, but also the indicative value from the analog measuring device(s) to the interrogator or reader, and then, becomes human readable value.
