摘　　要：Power amplifiers(PAs)play a crucial role in achieving key performance metrics such as efficiency,power,and linearity.However,in the millimeter-wave frequency range,the performance of active devices rapidly deteriorates with increasing frequency.The typical Doherty architecture,through load modulation techniques,can achieve high back-off efficiency^([1]).To enhance the linearity of the PA,adaptive bias circuits(ADBs)have been widely adopted^([2,3]).
