In the bottom left corner we have what looks like a die ID (D930 0001A) along with e-test features. These are two transistors with a common gate wire, which apparently has an ESD protection diode as well.

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.
