A new true-single-phase-clocking (TSPC) BiCMOS dynamic pipelined logic

Abstract

New true-single-phase-clocking BiCMOS dynamic logic circuits and BiCMOS dynamic latch logic circuits for high-speed dynamic pipelined system applications are proposed and analyzed. The circuit performance of the new BiCMOS dynamic logic circuits and BiCMOS dynamic latch logic circuits are simulated by using HSPICE in 1 mu m BiCMOS technology. Simulation results have shown that the operating frequency of the pipelined system which is constructed by the new dynamic latch logic circuits, is 204.1 MHz under 1.5 pF output loading at 2.3 V. It is 2.86 times of the operating frequency in the CMOS TSPC dynamic pipelined system.
