Resistance Compression Networks for Radio-Frequency Power Conversion

Radio Frequency Energy Harvesting Sources

“…In such cases, there is need to make the sensitivity of the rectifier circuits independent of the incident input power and variable output loads [35]. The use of resistance compression networks (RCN) have been proposed to address this scenario [63]. In a related sense, improved RF-DC conversion efficiency of rectifier circuits is witnessed when appropriate time varying signals with high peak-toaverage power ratio (PAPR) are employed [64].…”

High Efficiency Power Amplifiers for Modern Mobile Communications: The Load-Modulation Approach

“…This concept, founded on the principle of time-reversal duality [116], is illustrated in Figure 15. Following this approach, the Chireix output power combiner is modelled as a Resistance Compression Network (RCN) [117]. This class of networks, whose basic scheme is shown in Figure 16, allows for a direct derivation of the input network as a particular RCN, terminated with non-linear components R NL .…”

Rectenna Design and Signal Optimization for Electromagnetic Energy Harvesting and Wireless Power Transfer

“…Deviation from the design conditions causes the performance of the rectifier to degrade causing un-matching of the circuit and consequently reduction in RF-DC conversion efficiency. A circuit topology that has been proposed to overcome this problem is the use of resistance compression networks (RCN) [10], [11].…”

“…Structures that aim at maintaining the RF-DC conversion efficiency independently of variations in the input power level and output load time variations have been proposed [10], [11] based on resistance compression networks (RCN). Originally they have been used in DC-DC converter circuits to compensate for variations in the rectifier loads [10]. In [11] the use of a dual band RCN was proposed to be used in dual band rectifier circuits for energy harvesting and wireless power transfer.…”
