As current-voltage characteristics of GaAs MESFET differ from those of BJT and MOSFET and n-channel FET is only practically in use, the development of GaAs MESFET analog integrated circuits is left behind. In this paper, two circuit techniques to improve the performance of GaAs MESFET analog circuits are provided. The one is to realize a high impedance active load circuit which dose not need CMFB (Common Mode Feed Back) to achieve stable DC biasing point. The other is to cancel the harmonic distortion caused by nonlinear characteristics of GaAs MESFETs. As an application example of the proposed circuits, biquad low-pass and band-pass filters are realized and simulated by HSPICE to verify the validity of the proposed method.
