Abstract :
The impact of random telegraph noise on ring oscillator (ROSC) frequency was measured for the first time using an on-chip beat frequency detection system. The proposed differential sensing scheme achieves a high frequency measurement resolution (>0.01%) at a short sampling time (>1μs) allowing efficient collection of RTN induced frequency shifts. Experimental data from a ROSC array fabricated in a 65nm LP process display both single trap and multi-trap RTN behavior. The voltage dependencies of the frequency shift and capture/emission times were measured and analyzed.
