How to shrink giant resistors to fit in a small neural chip with quantum tunnelling
•8 min read
Neural amplifiers need teraohm resistors to block electrode drift, yet thousands must fit on a millimeter-scale die. Working up from the silicon lattice to the MOSFET, I show how quantum tunneling through a gate oxide turns a device flaw into an enormous, tunable resistor in the footprint of a single transistor.
