摘要：
A high performance power detector not only suited for monolithic structures, small in size, low in cost, and suitabed for broadband high frequency operations, but also excellent in the linearity of the detection characteristic, having a small fluctuation of detection characteristic relative to the bias fluctuation, having a small fluctuation of detection characteristic relative to the FET threshold voltage fluctuation, and in addition having a small DC offset wherein an additional circuit is unnecessary even if the latter stage circuit has a balance input, and a demodulator using the same.
