Capacitance Based Low Power ALU Design and Implementation on 28nm FPGA

In this work, capacitance and technology scaling is used for further reduction in IOs power. On 40nm technology and 10 GHz operating frequency, there is 4.59%, 9.38%, 13.97% and 18.76% reduction in IOs power when capacitance change from 5pF to 4pF, 3pF, 2pF and 1pF respectively. On 28nm technology and 10 GHz operating frequency, there is 5.54%, 11.32%, 16.86%, and 20.72% reduction in IOs power when capacitance changes from 5pF to 4pF, 3pF, 2pF and 1pF respectively. There is 17.16% and 17.99% reduction in power on 5pF and 4pF capacitance respectively on 10 GHz. There is 18.94%, 19.95% and 19.16% reduction in power on 3pF, 2pF and 1pF capacitance respectively on 10GHz. Target Device is Virtex-6 for 40nm and Artix-7 for 28nm.
