【発明の名称】乗算回路
Document Type and Number:
Japanese Patent JP2985993
Kind Code:
B2
Abstract:
PURPOSE:To provide the multiplying circuit by which multiplication of a small scale, and also, of high accuracy is possible. CONSTITUTION:The circuit is provided with a first and a second timers T1, T2 which have a characteristic by which an output voltage increases as an exponential function against time, and also, operate by the time corresponding to a difference of a reference voltage and an input voltage, and a third timer T3 having a characteristic by which an output voltage increases as an exponential function against time by using a voltage signal as an end trigger. To a first timer T1, a first input voltage (x) is inputted, and also, its output voltage is inputted as the reference voltage to a second timer T2, and to a second timer T2, a second input voltage (g) is inputted, and also, its output voltage is inputted as an end trigger to a third timer T3, and to a third timer T3, an operating signal of a first timer T1 is inputted as an input voltage.
