Fused booth encoder multiplexer

A fused Booth encoder multiplexer logic cell comprising:

• a logic circuit having a plurality of operand input bits including multiplier input bits and multiplicand input bits, a dynamic node, a clock input, a logic tree containing a plurality of logic transistors, each logic transistor in said logic tree having a gate connected to one of the operand input bits and said logic transistors being interconnected to carry out a Boolean function according to a Booth encoding and selection algorithm to produce a partial product bit for a multiplication operation at the dynamic node in a single clock phase, a power transistor coupling said logic tree to a voltage source, said power transistor being controlled by said clock input, a foot transistor coupling said logic tree to electrical ground, said foot transistor being controlled by said clock input, and a latch connected to said dynamic node which maintains the partial product bit at an output node, said latch being controlled by said clock input, wherein said latch includes:
• a first P-MOS transistor having a gate connected to said dynamic node, a source connected to said voltage source, and a drain;
• a second P-MOS transistor having a gate, a source connected to said voltage source, and a drain connected to said drain of said first P-MOS transistor;
• a first N-MOS transistor having a gate connected to said dynamic node, a source connected to said drains of said first and second P-MOS transistors, and a drain;
• a second N-MOS transistor having a gate connected to said clock input, a source connected to said drain of said first N-MOS transistor, and a drain connected to electrical ground;
• a third N-MOS transistor having a gate, a source connected to said drain of said first N-MOS transistor, and a drain connected to electrical ground;
• and
• an inverter having an input connected to said drains of said first and second P-MOS transistors, and an output connected to said gates of said first P-MOS transistor and said third N-MOS transistor, said inverter output being further connected to said output node to produce an inverted value;
• wherein said first P-MOS transistor and said first N-MOS transistor invert the value from the dynamic node, and the Boolean function of said logic tree accounts for inversion of the value by said first P-MOS transistor and said first N-MOS transistor.
