“…Q Ls is the quality factor of shunt inductor. R on and V DD are the switch resistance and supply voltage of the Class E PA. F and G are the power dissipation coefficients, and F = 2.3 and G = 1.7 are chosen to make the PA operate at the highest efficiency [27]. P out MFSK is the output power of Class E PA. As the energy consumption for the RF front end includes the energy consumption of PA and other blocks; the energy per bit can be expressed as …”

As is widely used in our daily life, wireless sensor network (WSN) is considered as one of the most important technologies of the new century. Although, the sensor nodes are usually battery powered with limited energy sources, the system energy consumption must be minimized in order to extend the life time. Since the energy consumption of transceiver front ends is dominant in the whole sensor nodes, we focus on how to minimize energy consumption by the system level design. According to the applications, we analyze four types of RF architectures: on-off keying (OOK) transceiver, phase-shift keying (PSK) transceiver, quadrature amplitude modulation (QAM) transceiver, and frequency-shift keying (FSK) transceiver which are widely used in WSN and establish the related energy models for each kind of architecture, respectively. We connect the baseband parameters such as modulation level, data rate, bandwidth, and propagation distance. With the energy consumption of RF front end for WSN. Afterwards, through theoretical and numerical analysis in system level, we discuss and conclude how to design optimal energyquality system in terms of various application scenarios.

A novel MEMS-based co-designed power amplifier is presented. To introduce the analysis and evaluate the impact of realistic on-chip losses, two design approaches are discussed and compared. Then the study of the novel circuit, based on the integration of high-Q BAW resonators with a Class E PA, is described. The integration method is explained, demonstrating how a careful co-design can allow to reach optimum performances. To confirm the theory a design example in a standard 0.18 μm CMOS technology is provided, showing an output power of 14.7 dBm and a drain efficiency up to 56% at 2.44 GHz.

This paper presents a new Class-E power amplifier (PA) with a -matching output network. The PA is targeted at low output power wireless applications. Analytical formulae are derived to aid the PA design, characterization and optimization. A fully integrated 2.4-GHz PA for short distance communications has been implemented in 0.13 m CMOS technology to verify the proposed design method. The measured output power levels vary from 3.2 to 5.7 dBm while achieving maximum overall efficiency of 55%.
