Abstract

A system according to one embodiment of the present invention includes a first clock signal generator generating a first clock signal at a first frequency, and a second clock signal generator generating a second clock signal at a second frequency that is higher than the first frequency. The first clock signal is used to calibrate the second clock signal generator. An RFID device according to another embodiment of the present invention includes a crystal controlled first clock signal generator generating a first clock signal at a first frequency, a second clock signal generator generating a second clock signal at a second frequency that is higher than the first frequency, and an activate circuit. The second clock signal generator is inactive until activated by the activate circuit. The first clock signal is used to calibrate the second clock signal generator. Methods are also presented.
