Abstract
A semiconductor integrated circuit includes a cascode circuit having a transistor, a detector circuit and a bias generator circuit. A bias is applied to a substrate of the transistor. The detector circuit generates a signal related to a threshold voltage of the transistor. The bias generator circuit generates the bias based on the signal generated by the detector circuit.
