“…The simple single-ended implementation makes lower insertion loss possible, but provides no common-mode TX-RX isolation. A power recycling technique has been proposed in [29] to recover part of the power lost in the balance network, effectively reducing the TX insertion loss. The performance of the proposed integrated duplexer is comparable to an off-chip SAW duplexer implementation with the added advantages of integration and tunability.…”

“…Unfortunately, with typical RF to DC circuit architectures, it is difficult to optimize both parameters at the same time because the sensitivity and PCE characteristics tend to work against each other. Thus, dynamic systems require the ability to dynamically track the available power over a wide range using MPPT techniques [73][74][75][76][77][78]. These techniques share the common requirement of having to measure input power, which is not a straightforward task in an ultra-low-power environment, as this functionality inevitably consumes further power and contributes to further reducing the PCE of the system.…”

“…In order to achieve high efficiency of the rectenna, a number of techniques such as harmonic rejection filter [15, 16] resistance compression networks [17, 18], and other different topologies [19, 20] have been implemented on the rectifying circuit. Recently, for efficiency improvement, the rectifying circuit with branch line coupler has been designed using an energy recovery methodology [21, 22].…”
