Publication number: 20020140492Abstract: A matching circuit that can protect a high frequency circuit from degradation in both output and efficiency, as well as from an increase of noise, changes of a frequency band even when an MIM insulation film thickness L around a subject transistor changes due to an unevenness among fabrication processes, thereby an electrical property of the transistor never changes among products, and provide a semiconductor device that employs such the matching circuit. An MIM capacity C1 is connected to an input side of the transistor so as to be combined with an input capacity of the transistor, thereby changes of the MIM insulation film thickness L can be eliminated automatically.
