Abstract

A monolithically integrated circuit, particularly an integrated circuit for radio frequency power applications, may include a transistor and a spiral inductor. The spiral inductor is arranged above the transistor. An electromagnetic coupling is created between the transistor and the inductor. The transistor may have a finger type layout to prevent any significant eddy currents caused by the electromagnetic coupling from occurring. The chip area needed for the circuit may be reduced by such arrangement.
