【発明の名称】演算回路
Document Type and Number:
Japanese Patent JP2972826
Kind Code:
B2
Abstract:
PURPOSE:To provide the arithmetic circuit which is small in scale and can perform highly precise power arithmetic and easily provide diverse arithmetic forms. CONSTITUTION:The ratio of time constants of 1st and 2nd RC circuits RC1 and RC2 which are charged with common reference voltage pulses RP is made correspond to an exponent and a threshold element Th1 is driven with the sum of the output voltage V1 and input voltage X of the 1st RC circuit RC1. The charging of the 2nd RC circuit RC2 is ended with the output S of this threshold element Th1.
