Abstract

In this paper, a new pass-transistor logic called the current-sensing complementary pass-transistor logic tree (CSCPTL) is proposed and investigated. The new logic circuit can be used in the low-voltage low-power system for high-speed applications. To exam the low-voltage applications, a 1.2V supply voltage is selected for one battery back-up systems. The current-sensing scheme yields a good sensing speed in small voltage swing than voltage sensing. But the dc power dissipation problem of the current mode circuit make it difficult to apply in low power applications. The new circuit can resolve the dc power problem in current-sensing scheme. The new circuit has superior speed performance with a power-delay product compared to LCPL which is acknowledged to have the most potential in low-voltage low-power digital circuits design. The CSCPTL can be operated at 1.2V without changing conventional 5V CMOS process.
