OSCILLATION CIRCUIT

摘要

A first wiring layer, and a plurality of second wiring layers thinner than the first wiring layer are formed in lamination on a semiconductor substrate. An inductor is constituted of the plurality of second wiring layers. The inductor oscillates at such a frequency that the inductor and a parasitic capacitor of an inverter circuit resonate. An n-type MISFET and a p-type MISFET of the inverter circuit have drains connected mutually, and the output of the inductor is connected to the connection point of the drains.
