Design of a low-voltage reference circuit with reconfigurable temperature range for rfid applications

This paper describes the design of a current-mode bandgap for RFID applications. Its temperature compensation network can be set between two states which enables different compensation criteria. In the first state the temperature dependent behavior is optimized around ambient temperature, in the other state a better adaption at the higher temperature range can be achieved. The chip is designed in a 0.13µm CMOS technology. It was developed at the Institute for Electronics Engineering within the scope of a research project supported by the Bavarian Research Foundation.
