Someimprovments on the last Design: • Ripple Carry Adder CSA with CLA • Multiplier still thesame one: Array Multiplier CSA CLA Sum
Design factorsforASIC‘s • Max Freq. : 250 … 500 MHz • LeackagePower: 1.0… 4.7uW • SupplyVoltage: 1.0 – 2.0 V • Optimization : Area, Speed, andleakage Power • Result: • IncreasetheVoltage moreLeakage Power but fasterdesign
Leakage Power vs. Supply Voltage
