摘要： An impedance conversion circuit wherein source-follower circuits are formed at the input side and at the output side, between the first source-follower circuit (input side) and the second source-follower circuit (output side), a signal transmission circuit is constructed by connecting two FETs. In this circuit the threshold voltages of the FETs and variation of the threshold voltages can be offset, whereby the output voltage becomes equal to the imput voltage regardless of fluctuations of the threshold voltage or temperature, thereby retaining the voltage constant during impedance conversion from a high input impedance to a low output impedance.
