Exponent a arithmetic circuit and implementation method thereof

摘要: The invention discloses an arithmetic circuit of a general exponent and implementation method thereof, solves the problem that present is only for realizing natural exponential function e in shortage exponents . According to invention, implemented through mathematics equivalent relation =e , consisting both diode D1 integrated arithmetical amplifier U1 utilized realize logarithm 1na, multiplier U2 voltage product xlna arithmetic, D2 so as arithmetic. provided by types analog signal circuits are increased, range expanded. simple structure, accurate good stability, can not signals but also such > expanded manner, has broad application prospect circuits.
