Claim 12:
13. A digitally-controlled oscillator comprising:
an upper unit and a lower unit that are connected in series between a power line and a ground line; and
a variable capacitor that is connected to at least one of the upper unit and the lower unit,
wherein each of the upper unit and the lower unit includes a pair of circuit elements that are cross-coupled and an inductor connected to the pair of circuit elements,
wherein the inductor of the upper unit and the inductor of the lower unit are combined to form a trans-configuration, and
wherein the digitally-controlled oscillator further comprises a capacitor that is connected to a connection node of the upper unit and the lower unit, the connection node being a virtual ground node of the upper unit.
