Circuits and Methods to harvest energy from transient on-chip data

Circuits and methods that harvest electrostatic energy from transient on-chip data are described in the Application. In one aspect, a method and inverter circuit harvests electrostatic charge held at its output node at an electric potential comparable to the power supply voltage rail to a common grid/node as the output makes a 1→0 logic transition. This charge harvested at a common grid/node can be used by circuits (described in applications 63/090,169, 63/139,744) to drive 0→1 logic transition at their output nodes at lower energy drain from the on-chip power grid than a conventional CMOS inverter would with similar performance, slew rates at inverter input and output and with similar output driving transistor geometries.
