Abstract	This work presents a new all CMOS Self-Compensated Oscillator (SCO) that is highly stable across temperature and is utilized as a reference clock source. The new architecture utilizes an innovative phase shift technique that adjusts the phase of the tank at a specific Temperature Null (TNULL) phase where the frequency deviation across temperature is minimized. The single LC tank architecture used in the new oscillator reduces die area significantly compared to a previously reported dual LC tank architecture. The new oscillator achieves a total frequency stability of ±100ppm across temperature (−40–85°C), supply (3.0–3.6V) and load (0–15pF). CMOS output frequencies from 1–133MHz can be produced with a 2.8ps rms period jitter and 7mA current consumption at 25MHz output.
