Ok - a fair point. "Voltage squared" fits better, indeed. It's a simplification that comes from P = V * V / R.

- whatshisface 7y agoThe word you're looking for is "quadratically."
- stcredzero 7y agoThanks for that! Now I can use parallel -ly suffixes to express that thought, too!
- xxs 7y agoTrue that, but what bothers me is that people may take it 'as 4x times increase' (quad=4, similar to twice, thrice, and so on). This is pretty much what I used to use.
- whatshisface 7y agoThat's called "quadrupling."
- verall 7y agoThat's not right - it comes from the formula of power dissipation in an asic: P=CfV^2 (power equals capactiance times frequency times voltage squared). Clearly we don't turn all the mosfets on every cycle but it's the rough idea.
- xxs 7y agoeh, c'mon; 1/R = 2πfC <- which is exactly the same. I tried to show where the voltage comes from with a well known formula. About turning on/off all fets, it doesn't matter as long as the same ones turn on in specific cycles. They just turn on/off more frequently.
