| PURPOSE: A device for converting a digital signal into an analog signal is provided, which performs a digital/analog conversion function and also performs calculations like addition and subtraction, without using an additional circuit. CONSTITUTION: The device converts N>= 2 digital signals of M bits into analog signals. The device comprises M nodes(n21,n22,...,n2M), and (M-1) first capacitors being connected between the mth node and the (m+1)th node and having a capacitance of 2NC, and N second capacitor groups comprising M second transistors respectively, and the third transistor(105) whose one end is connected to the first node and another end is connected to a ground voltage port and has a capacitance of NC. | ||||||
