Abstract

PURPOSE: To improve the retaining characteristic of a voltage retaining circuit by utilizing complementarity of the voltage rise and voltage down through the use of two capacitors.
CONSTITUTION: The change voltage 1 is applied to a capacitor 3 through a memory switch 2 to charge it and, further this charge is sent to a capacitor 4 through the switch 2, a resistance 9. Thus, the terminal voltage of the capacitor 3 and 4 are added by an adder 7 to take out an output 8. In this way, since the voltage down of the capacitor 3 and the voltage rise of the capacitor 4 are complementary, in the synthesized output, the retaining characteristic just after starting retain is good and the excellent retaining characteristic is obtained.
