| Abstract: | The linearity of the power amplifier can be effectively improved by use of capacitance-compensation technique.The design of power amplifier using capacitance-compensation technique for 5.25 GHz WLAN is described.The technique is applied to a full differential two-stage amplifier,and then the input-output matching network is designed.Then the global simulation is completed by the ADS software.The results show that,with 1.8 V supply voltage,the output 1 dB compression point of the improved PA has 5 dB increas... |
