A method of fabricating an integrated circuit with a transistor having less susceptibility to off-state leakage current and short-channel effect is disclosed. A bias circuit used as for biasing the gate of a final-stage power transistor is included in a power amplifier provided in a communication mobile system. Each of the ribs 11A has an opposed edge 11C and a side edge. The encoder groups multiple windows from different channels into one or more tiles and outputs tile configuration information, which allows the encoder to isolate transients that appear in a particular channel with small windows, but use large windows in other channels. The second transistor also includes a second source node and a second gate node. A compound or a pharmaceutically acceptable salt thereof, which compound is represented by the formula below.
