Abstract :
This paper proposes a low-power two-variable logic circuit based on mixed voltage-mode/current-mode logic design. The voltage- and current-mode operations can be selected for low power consumption at low and high frequency, respectively, according to speed requirement. An nMOS pass transistor network is shared to realize voltage switching and current steering for the voltage- and current-mode operations, respectively, which leads to high utilization of the hardware resources. As a result, the power consumption of the hybrid two-variable logic circuit is lower than that of the conventional two-input look-up table (LUT) using CMOS transmission gates, when the operating frequency is more than 800 MHz. The delay and area of the hybrid two-variable logic circuit are increased by only 7% and 13%, respectively.
