Abstract :
A recursive scheme for the 2D Taylor-series coefficient evaluation of MESFET drain current characteristics is proposed by using low-frequency harmonic power measurements with the associated phase polarity information. The formulation is in a systematic approach to acquire the general expressions for various order terms. Numerical studies examine the validity of the proposed method with additional measurement uncertainty simulations. Experimental verifications with the two-tone intermodulation distortion of a MESFET amplifier are also shown.
