A new CMOS current-sensing complementary pass-transistor logic (CSCPTL) for high-speed low-voltage applications

[[abstract]]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 low-voltage low-power systems for high-speed applications. To examine the low-voltage applications, a 1.2 V supply voltage is selected for one battery back-up systems. The current-sensing scheme yields a good sensing speed with small voltage swing. The dc power dissipation of the current mode circuit makes it difficult to apply in low power applications. The new circuit can resolve the dc power problem in the current-sensing scheme. The new circuit has superior speed performance with a power-delay product comparable to LCPL which is acknowledged to have the most potential in low-voltage low-power digital circuits design. The CSCPTL can be operated at 1.2 V without changing the conventional 5 V CMOS process.[[conferencetype]]國際[[conferencedate]]19950428~19950503[[booktype]]紙本[[conferencelocation]]Seattle, WA, US
