DC Bias Current Delivery Lab

ERSFQ can kill static resistor heat — it does not erase I_total ∼ N · I_b under parallel feed. Amperes are a cryocable / delivery problem.

ERSFQ clears amps?

Room-temp supply → cryocable → on-chip taps → return

Illustrative I_b only (not a PDK). Serial recycle cartoon: I_supply ∼ I_b with stacked ground islands — next concept card. Pads for timing still grow N in the parallel sum.
