At the bottom of the die are several pieces of special CMOS circuitry, I suspect this is where the VCO lives. Several prominent capacitor structures can be seen, formed between the poly layer and the substrate.

The standard cell library used elsewhere on the die looks rather unusual; both poly and diffusion features make large excursions outside power distribution rails. At the top of the snippet is what looks like an autorouter bug.
