Abstract Noise sources of the junction type PET and formulas for them are presented. These are practical formulas for common source, common grid and common drain for the PET in low, medium and high frequency regions, they being obtained by use of the Y admittance model. Also, a comparison is made of noise characteristics of the three configurations of the FET, from which certain principles in low noise design are suggested.
