“…Such efficient designs require a system approach from which each component that constitutes an IoT system will be carefully designed [24], as shown in Figure 1. Current research works in circuits and systems' efficiency mostly focus on the design of efficient protocols or architectures for communication Integrated Circuit (IC) [25][26][27][28], or on more efficient power management systems [29][30][31], but they usually do not include efficient integration of the proposed IC into a comprehensive IoT system. In this way, the design of the front end IC usually aims to meet an impedance of 50 Ω, such that the design of the transmission line and the matching circuit or antenna can be reduced to the choice of components with characteristic impedance equal 50 Ω.…”

Within an increasingly connected world, the exponential growth in the deployment of Internet of Things (IoT) applications presents a significant challenge in power and data transfer optimisation. Currently, the maximization of Radio Frequency (RF) system power gain depends on the design of efficient, commercial chips, and on the integration of these chips by using complex RF simulations to verify bespoke configurations. However, even if a standard 50Ω transmitter’s chip has an efficiency of 90%, the overall power efficiency of the RF system can be reduced by 10% if coupled with a standard antenna of 72Ω. Hence, it is necessary for scalable IoT networks to have optimal RF system design for every transceiver: for example, impedance mismatching between a transmitter’s antenna and chip leads to a significant reduction of the corresponding RF system’s overall power efficiency. This work presents a versatile design framework, based on well-known theoretical methods (i.e., transducer gain, power wave approach, transmission line theory), for the optimal design in terms of power delivered to a load of a typical RF system, which consists of an antenna, a matching network, a load (e.g., integrated circuit) and transmission lines which connect all these parts. The aim of this design framework is not only to reduce the computational effort needed for the design and prototyping of power efficient RF systems, but also to increase the accuracy of the analysis, based on the explanatory analysis within our design framework. Simulated and measured results verify the accuracy of this proposed design framework over a 0–4 GHz spectrum. Finally, a case study based on the design of an RF system for Bluetooth applications demonstrates the benefits of this RF design framework.

“…inductors. By integrating these elements on single chip together with CMOS components, the tuning range may be improved (Ryckaert et al, 2005;Li et al, 2005;Tseng et al, 2007). The performance measure of an oscillator is its quality factor, that is, the ratio of the resonant frequency peak to its spectral bandwidth.This performance indicator can be improved by decreasing the phase noise, since quality factor and the phase noise are inversely proportional to each other.…”

This paper presents the design and analysis of a novel 2.4 GHz Voltage Controlled Oscillator (VCO), with amplitude control and Q enhancement circuit, for wireless communication applications. The variable capacitors and the inductors were designed using ANSYS and imported through DAC components in ADS (Advanced Design software). Accurate simulation of the VCO was performed in the software environments and the results are provided. To enhance the quality factor and to control the oscillation amplitude, additional CMOS circuits have been implemented. This VCO operates at 2.4 GHz, achieves a phase noise of -119dBc/Hz, 3 MHz far from the carrier frequency. The VCO produces frequency tuning from 1.82 to 2.60 GHz (32.5%) with an ultra low power consumption of 73 µW. The output power level of the VCO is -9 dBm, with an improved predicted quality factor of 77.
