Basics power anaysis

Power

• Dynamic power:
• Power consumed by the cell when it is active mode.
• Switching Power:
• Power dissipated by the charging and discharging of the output load capacitance of a cell is called switching power.
• Switching power of a cell is a function of output load capacitance and the rate of logic transitions.
• Internal Power:
• Power dissipated by charging and discharging of internal capacitance within the boundary of the cell is called Internal power.
• Short circuit power
• Power dissipated when a small amount of time both the PMOS and NMOS transistors are turns on.
• there is short circuit established from VDD to VSS.
• Leakage power
  
• Power dissipated by the cell or circuit when it is in stand by mod or inactive mode.
