New high-speed BiCMOS current mode logic (BCML) circuits for fast carry propagation and generation are described. These circuits are suitable for reduced supply voltage of 3.3-V. A 32-b BiCMOS carry selected adder (CSA) is designed using 0.5-/spl mu/m BiCMOS technology. The BCML circuits are used for the correct carry path for high-speed operation while the rest of the adder is implemented in CMOS to achieve high density and low power dissipation. Simulation results show that the BiCMOS CSA outperforms ECL and CMOS adders.
