A new multiple-valued current-mode (MVCM) integrated circuit using a switched current-source control technique is proposed fora 1.5 V-supply high-speed arithmetic circuit with low-power dissipation. The use of a differential logic circuit (DLC) with a pair of dual-rail inputs makes the input voltage swing small, which results in a high driving capability at a lower supply voltage, while having large static power dissipation. In the proposed DLC using a switched current control technique, the static power dissipation can be greatly reduced because current sources in non-active circuit blocks are turned off. Since the gate of each current source is directly controlled by using a multiphase clock whose technique has been already used in dynamic circuit design, no additional transistors are required for currentsource control. As a typical example of arithmetic circuits, a new 1.5 V-supply 54 x 54-bit multiplier based on a 0.8/im standard CMOS technology is also designed. Its performance is about 1.3 times faster than that of a binary fastest multiplier under the normalized power dissipation. A prototype chip is also fabricated to confirm the basic operation of the proposed MVCM integrated circuit.
