In the power-saving mode, when the received power is greater than the sensitivity of the Rx module, the excess power is directed to the EH load (power storage), while the Rx direction is still in place. The fact that the proposed MSNC can manage the received power level smartly and without any external control, distinguishes the proposed MSNC from other EH circuits. The proposed MSNC operates within a power range from-50 to +15 dBm, demonstrates an efficiency of more than 60% in the power-saving mode, and has acceptable matching over a large frequency range. The design procedure of the proposed MSNC along with the theoretical, simulation, and measurement results are presented in this article. Good agreement between theory, simulation, and measurement results confirms the accuracy of the design procedure.

Abstract:

In this article, a multimode smart nonlinear circuit (MSNC) for wireless communications (transmitting (Tx) and receiving (Rx) modes) as well as energy harvesting (EH) and power saving is presented. The proposed MSNC is designed at 680 MHz and has three ports, which are connected to an antenna, T/R (transceiver), and power-saving modules. According to the input-output power level, the proposed MSNC has three modes of operations: Rx, power saving, and Tx, for low ( < !!-25 dBm), mid (>!!-25 and < 0 dBm), and high (>5 dBm) power ranges, respectively. In the power-saving mode, when the received power is greater than the sensitivity of the Rx module, the excess power is directed to the EH load (power storage), while the Rx direction is still in place. The fact that the proposed MSNC can manage the received power level smartly and without any external control, distinguishes the proposed MSNC from other EH circuits. The proposed MSNC operates within a power range from-50 to +15 dBm, demonstrates an efficiency of more than 60% in the power-saving mode, and has acceptable matching over a large frequency range. The design procedure of the proposed MSNC along with the theoretical, simulation, and measurement results are presented in this article. Good agreement between theory, simulation, and measurement results confirms the accuracy of the design procedure.
