Work out static leakage power instantly with clear inputs, formula shown and shareable results.
Sub-threshold leakage roughly doubles every 10 degrees of junction temperature, so a chip at 85 degrees leaks about 64 times as much as the same chip at 25. That exponential coupling creates thermal runaway risk: leakage heats the die, which increases leakage further.
Leakage power
P_leak = N x I_leak x V, with I_leak roughly doubling per 10 degrees C rise
At advanced nodes it can be 30-50% of total power. It flows whether the circuit is working or not, so it directly attacks battery life in idle states.
Power gating idle blocks, multi-threshold cells (high-Vt on non-critical paths), body biasing, and keeping junction temperature down.
