 Hi Rajneesh

   The power is related to capacitance, frequence and voltage. P =3D =
C*f*V^2, so if you apply 1.5V the power will be much lower than if you =
apply 3.3V.

Subject: [SI-LIST] - Difference between High Current Low Voltage and Low
Current High Voltage circuits


Hello All,

My apologies as I feel this question may not be directly related to
SI-LIST.

Today's processors are using very low voltages at high currents (e.g.
currents in the range of 20-30 A at 1.2 to 1.5 V of core operation). I
would like to know whether the manufacturers of chips get any additional
benefit by going to high currents at low voltages. What will be the
situation like if you use low currents at high voltages (say 3.3V or
5V)? My premise is that the power consumption being the product of
voltage and current is the same (e.g. 20A @ 1.5V is the same as 9.09A @
3.3V).

Regards,
Rajneesh
