Abstract

In this paper, we develop an integrated CMOS microwave energy converter for passive wireless microdevices. A modification of the voltage multiplier circuit, which allows implementing a device efficient in multiplication using standard CMOS technologies, is proposed. Compact models of multistage multipliers that take into account the voltage drops across nanoscale MOS transistors when operating in regions of weak and strong inversion are presented. The converter’s operation at 2.45 GHz is studied at various input power levels, including extremely low levels. It is established that, for the typical 90-nm CMOS technology, the device can operate at extremely low input power levels (less than –20 dBm), which allows wireless systems to operate both at a considerable distance from the base station and when collecting radio-frequency (RF) radiation energy from the environment.

集成式CMOS微波功率转换器,用于无源无线设备

摘要

在本文中,我们为无源无线微型设备开发了集成的CMOS微波能量转换器。提出了对电压倍增电路的修改,该修改允许使用标准的CMOS技术实现高效的乘法器件。提出了紧凑的多级乘法器模型,该模型考虑了在弱反转和强反转区域工作时跨纳米MOS晶体管的压降。在各种输入功率水平(包括极低的水平)下研究了转换器在2.45 GHz频率下的工作情况。已经确定,对于典型的90nm CMOS技术,该设备可以在极低的输入功率水平(小于–20 dBm)下工作,
