“…Manufacturers strive for a single-chip solution using a CMOS-based technology for cost reasons [15,19]. The main advantages of using power devices for the RF power amplifier with operating voltages well above the CMOS level (typically 3.3 V or below) arises from the reduction of device current for the required output power of 1-3 W. This would both minimize electromigration effects through the metallization layers and the impact of parasitic inductances [20]. Therefore, it can be expected that the trend towards a fully integrated fabrication with LDMOS transistors will also be used in RF power amplifiers for mobile phones in the near future.…”

This chapter deals with applications for power electronics using integrated circuits, providing intuitive access to lateral power transistors employed therein. For this purpose so-called smart-power ICs combining logic operation, memory and power electronic circuitry are presently employed. Additionally, integrated lateral power transistors are also the driving force in multi-stage RF power amplifiers (monolithic microwave integrated circuits) for base stations with a clear trend towards further incorporation of logic functionality and the implementation in the power amplifiers of mobile devices.An overview of power electronic and power amplifier markets provides a basic understanding for the applications driven by these technologies and the implications involved in rolling out new developments. In particular, the impact of power electronics on energy conversion and the impact of power amplifiers on information technologies are presented. Power electronic and RF amplifier applications having a high impact on recent developments using integrated circuits are briefly reviewed. Examples of power electronic applications include motor control and drive inverters for window lifts in automobiles and switch-mode power supplies in battery chargers. Integrated circuits for radio-frequency (RF) applications are readily found in mobile communication base stations and in wireless local area network (WLAN) communication equipment.Subsequently, the requirements of these applications regarding their commercial use will be summarized. This overview includes economic aspects like energy efficiency, reliability as well as costs of fabrication and operation. Moreover, technologically relevant aspects regarding power density, ruggedness and switching frequency will be elaborated upon. Semiconductors in Integrated Power Electronics and Radio Frequency AmplifiersOne of the key enabling technologies for the success of monolithic integrated power electronic systems and RF applications has been the lateral double-diffused metaloxide-semiconductor (LDMOS) field-effect transistor in silicon technology which
