Exponential ax operational circuit

摘要: The utility model discloses an exponential ax operational circuit. At present, existing circuit is only the for achieving natural functions, and a common lacks. According to circuit, mathematic equivalent relation of = exlna used operation composed diode D1 integrated amplifier U1 logarithms lna, multiplying unit U2 voltage products xlna, D2 exponentials exlna, namely achieved. types analog signal circuits are increased, range signals widened, structure simple, precise, stability good, operations can be achieved by such as axy (img file ' DDA0000516518840000011. TIF' wi '57' he 56' /) extended achieved, wide application prospect in circuits.
