Abstract

This paper presents a new programmable voltage adder/subtractor circuit. The proposed circuit is based on differential difference current conveyors and MOS switches. The adder/subtractor yields advantages over previous adders and subtractors in view of the less active components, low power consumption and its function to be programmable by digital codes which is suitable for integrated circuit implementation. Simulation results using PSPICE program are also obtained. From simulation results, it finds that the operation range of the proposed adder/subtractor is ±1.5 V with a supply voltage of ±2V and the operation frequency is up to 100 MHz.
