01 ·Device Physics·★ MEMBER·10 min read Reading Chip Design as a Power Budget — The Physics of Leakage and Heat A modern chip is limited not by what fits, but by how much of it can be lit at once. This piece reads that limit as a household budget: dynamic power versus leakage, the positive feedback that makes leakage swell with temperature, the thermal resistance that converts watts into degrees, and the three — and only three — ways a designer can spend the watts. 02 ·Scaling & Power·★ MEMBER·9 min read The Physics of Power — Why Lowering Voltage Pays So Much Derive what one switching event costs, then read the dynamic power equation to see why voltage alone enters squared. From there: Dennard scaling and its end, the 60 mV/decade thermodynamic floor, dark silicon, and the resulting turn toward fixed-function circuits and low precision — ending with the arithmetic of what inference costs to run.
