Summary:This paper reports on the design of a low-power high-accuracy oscillator intended to serve as a clock reference for passive RFID tag. For this purpose, we have proposed an RC oscillator scheme adopting the efficient and robust resistor calibration. This novel calibration technique allows to achieving a frequency variation of only ±2.5% in the worst case, according to our 405 corners (PVT variation) simulation. It also shows that the power consumption is only 800nW, and its overall figure-of-merit exceeds most of the state-of-art circuits.
