“…Ho and Luong (2003) introduced a differential class-E PA with a low supply voltage of 1 V, as shown in Figure 11 [41]. This architecture displayed a large capacitive loading when it used millimeter-size transistors because of the low supply voltage.…”

“…In addition, the output power was doubled from that under a single-ended configuration, and the optimum load was reduced. Consequently, the matching losses were reduced [41]. The size of the transistors and the current flowing can be reduced by using a differential configuration.…”

Power amplifiers (PAs) are among the most crucial functional blocks in the radio frequency (RF) frontend for reliable wireless communication. PAs amplify and boost the input signal to the required output power. The signal is amplified to make it sufficiently high for the transmitter to propagate the required distance to the receiver. Attempted advancements of PA have focused on attaining high-performance RF signals for transmitters. Such PAs are expected to require low power consumption while producing a relatively high output power with a high efficiency. However, current PA designs in nanometer and micrometer complementary metal–oxide semiconductor (CMOS) technology present inevitable drawbacks, such as oxide breakdown and hot electron effect. A well-defined architecture, including a linear and simple functional block synthesis, is critical in designing CMOS PA for various applications. This article describes the different state-of-the art design architectures of CMOS PA, including their circuit operations, and analyzes the performance of PAs for 2.4 GHz ISM (industrial, scientific, and medical) band applications.

“…The real-time location system is used to track the items and it can be used for the identification of the position of the objects in real time with the help of tags or devices (Subhan, Hasbullah, Rozyyev, & Bakhsh, 2012). Theses tags or devices are fixed in the objects that receive the wireless signals (Ka-Wai & Luong, 2003).…”

Limited resources and network dynamicity are challenging issues in Bluetooth networks. Therefore, scatternet formation improvement and efficient routing algorithms are required that can efficiently construct a short route between a source and destination. As of today, many protocols have been proposed, mostly researchers focusing on simplicity and reliability, but only few of them fulfill the Bluetooth scatternet scenario. Therefore, it opens new doors for scatternet formation and inter-piconet routing for the Bluetooth scatternet. This paper presents a review of Bluetooth routing and scatternet formation protocols for inter-piconet communication. First, Bluetooth operation is explained followed by important applications and topologies are discussed. Then, inter-piconet routing and network formation protocols are critically analyzed. Finally, Bluetooth problems and open research issues are highlighted.
