Electronic circuits powered at ultra low voltages (500 mV and below) are desirable for their low energy and power consumption. However, RTN (Random Telegraph Noise)-induced threshold voltage variations become very significant at such supply voltages. This paper evaluates the impact of RTN on additional jitter in a ring oscillator. Since FDSOI allows a large range of body bias voltages, this work studies how body biasing affects the oscillation frequency but also the jitter effects. The impact of RTN in NMOS and PMOS devices on frequency as well as the levels of supplementary jitter introduced by RTN are evaluated and compared with classical device noise.
