Design of Low Voltage High Linearity Driver Amplifier Chip Base on GaAs
This paper describes a 0.4～1.1 GHz broadband low-voltage hign linearity amplifier Chip based on GaAs HBT process and its onwafertest result.The chip uses active biasing and parallel negative feedback technology combined with libear capacitance,and a ballast resistor is added to the emitter to enable the amplifier to achieve high linearity,low operating voltage and good gain flatness within the operating frequency band,while reducing the effect of small process fluctuations on amplifier performance.
