method and circuit for removable singularities in translinearen loops coupled to disturb

摘要

PROBLEM TO BE SOLVED: To reduce or remove an influence of a removable singular point in the operation of a translinear loop.;SOLUTION: A translinear network 34 includes first translinear loops (Q₁, Q₂, Q₃, Q₄) and second translinear loops (Q₄, Q₃, Q₅, Q₆). A circuit 36 of a Trafton-Hastings clamp is connected to generate a sectional-polynomial-continuous current I_Y and in a current I_X=0, its value is made indefinite by the removable singular point in a transfer equation in this point. A current mirror 38 equipped with a plurality of transistors (M₁, M₂, M₃) is connected to the circuit 36 of the Trafton Hastings clamp and is operated to further apply currents of transistors Q₃ and Q₅ to I_X when conducting a transistor Q₇ of the Trafton-Hastings clamp, thereby perturbing the removable singular point in the transfer equation to a left half plane.;COPYRIGHT: (C)2004,JPO&NCIPI
