Abstract

　低雑音増幅器は，ゲートに高周波入力信号が入力されるソース接地トランジスタ（M1）と，ソース接地トランジスタのドレインの高周波信号がソースに入力されるゲート接地トランジスタ（M2）と，ゲート接地トランジスタのドレインと電源電圧との間に設けられた負荷共振回路(LoCo)と，ソース接地トランジスタのドレインとゲート接地トランジスタのソースとの間に設けられ，直流成分には実効的にオープンで高周波成分には実効的にショートになる結合エレメント（C1）と，ソース接地トランジスタのドレインと電源電圧との間に設けられソース接地トランジスタのドレインにバイアス電圧を供給するバイアス供給用インダクタ（Lm1）と，ゲート接地トランジスタのソースに接続されゲート接地トランジスタにバイアス電流を供給するバイアス供給用電流源(Im2)とを有する。
