Claim 5:
6. The oscillation circuit of claim 5, wherein the first AGC circuit comprises:
a second p-type transistor having a source coupled to the power supply rail;
a second n-type transistor having a source coupled to the reference potential node and having a drain coupled to a drain of the second p-type transistor;
a third p-type transistor having a source coupled to the power supply rail and having a gate coupled to a drain of the third p-type transistor, to a gate of the second p-type transistor, and to a gate of the first p-type transistor;
a third n-type transistor having a drain coupled to the drain and the gate of the third p-type transistor; and
a first resistive element coupled between a source of the third n-type transistor and the reference potential node.
