Abstract :
A 3 bits - 0.25 μm BiCMOS SiGe:C accumulator operating up to 15 GHz clock frequency is presented. It is based on a high-speed and low-power three-levels BiCMOS logic which is used to implement the 1 bit full-adder and the D-flip-flop latch-up register. With this technique, the dissipated power is reduced by 30% over the usual four-levels series logic. The circuit integrates 203 (without buffers, 230 with) transistors and dissipates 67 mW (without buffers, 119 with) from a 2.7 V supply.
