O. Cicekoglu et H. Kuntman, NOVEL QUAD STRUCTURE FOR REALIZATION OF LOW-DISTORTION ANALOG MULTIPLIER, International journal of electronics, 85(1), 1998, pp. 79-85
In this paper, a novel low-distortion quad structure is proposed which
can easily be implemented in the design of low-distortion analogue mu
ltipliers. Starting from a highly-accurate BJT model, expressions to c
alculate the harmonic distortion coefficients for the proposed circuit
are derived. Theoretical results are proved by experiment.
