Low Power Compact GaAs PHEMT Level Converter for Digital Control Logics of GaAs Switches
Wei Chen, Hao Luo, Min Zhou, Zhe-Ming Lu, Yong-Heng Shang and Fa-Xin Yu

Abstract:
In this study a level converter based on GaAs pHEMT technology for a MFC (Multifunctional Chip) is designed, simulated and tested for the application of T/R (Transmit/Receive) module for an X band phase array radar system. It has the advantages of smaller chip size, lower power consumption, higher efficiency, lower cost and high stability. The circuit design is based on a feedback and feed-forward network which compensates the chip process variations during the wafer fabrication and operation temperature changing. It results the designed chip has a high stability. Its supply voltage is -5 v with a shared bias generator, this allows reducing the power consumption compared with the other design at -7.5 v in the literature. The testing results have shown that the proposed novel design has met all the specifications given in this project.
