[Abstract]:The traditional silicon-based CMOS integration technology follows Moore's law to improve the working speed of the device, increase the integration and reduce the cost by continuously reducing the characteristic size. However, after entering the nano-era, Ingaas MOSFET has become the research focus of the next generation CMOS technology because of its superior electron mobility. This paper is mainly based on the device and its manufacturing process of the Institute of Microelectronics of the Chinese Academy of Sciences. Based on the design of InGaAs MOSFET power device and RF class E power amplifier, the following research work has been carried out: 1. Based on the process conditions of Institute of Microelectronics, Chinese Academy of Sciences, the design and fabrication of InGaAs MOSFET power device are completed, and the research of GaAs back hole process is completed, and the complete InGaAs MOSFET MMIC fabrication process is realized. 2. The fabrication of 50 惟 /-TaN thin film resistance, Si3N4MIM capacitance and spiral inductor passive devices compatible with In GaAs MOSFET process is studied and completed. Based on the test of MIM capacitance and spiral inductance and MOM simulation data, the modeling of capacitance and inductance is completed. At the same time, the relationship between the thickness of Al2O3 dielectric and the DC and RF characteristics of MIM capacitance is also studied, which makes a certain basis for the application of Al2O3 dielectric MIM capacitance in InGaAs MOSFET MMIC circuit. The modeling process of InGaAs MOSFET from small signal model to large signal model is completed. According to the structure of InGaAs MOSFET power device, the equivalent topological structure of small signal model is established, and the direct extraction method of small signal model parameters is proposed. IC-CAP modeling software and ADS simulation software are used to model and fit the EEHEMT large signal model of InGaAs MOSFET. 4. Based on the large signal model of InGaAs MOSFET power device, the simulation design of two-stage RF E power amplifier is completed. The power amplifier operates at a frequency of 2.45 GHz~2.55 GHz,P1dB30dBm,Gain27dB,PAE65%. at 4V drain voltage and-1.2V gate operating voltage.
