Summary:
This paper proposes a new linear low-gm OTA. The advantages of the proposed OTA are the simple structure, and easiness of design. In addition, it should be noticed that input signal attenuator with precise coefficient is not necessary. The optimum value of the linearization parameter K is obtained theoretically from maximally flat approximation without relying on numerical analysis. Simulation results show that the linearity of the proposed OTA is about the same as the conventional OTA.
