Abstract—An on-chip frequency reference exploiting the well-
defined thermal-diffusivity (TD) of IC-grade silicon has been re-
alized in a standard 0.7
m CMOS process. A frequency-locked
loop (FLL) locks the frequency of a digitally controlled oscillator
(DCO) to the process-insensitive phase shift of an electrothermal
filter (ETF). The ETF’s phase shift is determined by i
