| 26.4 Components Of Power Dissipation |
| Unlike bipolar technologies, where a majority of power dissipation is static, the bulk of power dissipation in properly designed CMOS circuits is the dynamic charging and discharging of capacitances. Thus, a majority of the low power design methodology is dedicated to reducing this predominant factor of power dissipation. |

| There are three main sources of power dissipation: |
- Static power dissipation (PS)
- Dynamic power dissipation (DS)
- Short circuit power dissipation (PSC)
|
Thus the total power dissipation,  , is |
