Abstract :
This paper presents a realization of an ultra low power ring oscillator in 0.14 mum bulk CMOS technology. The application field for this oscillator is the clock generation for a baseband processor of a passive ultra high frequency (UHF) radio frequency identification (RFID) transponder. This technology will play an important role in the field of automatic identification. The paper contains simulation and measurement results for tuning range, cycle to cycle jitter and power consumption with regarding to the control current and supply voltage. The circuit was designed and fabricated by using 0.14 mum bulk CMOS technology.
