What is the significance of switching energy?

In subthreshold operation, the current drops exponentially as VDD – Vt decreases and thus the delay increases exponentially. The switching energy improves quadratically with VDD. Leakage current improves slowly with VDD because of DIBL, but the leakage energy
increases exponentially because the slower gate leaks for a longer time. To achieve minimum energy operation, all transistors should be minimum width. This reduces both switching capacitance and leakage. Gate and junction leakage and short-circuit power are
negligible in subthreshold operation, so the total energy is the sum of the switching and leakage energy, which is minimized near the point they crossover.
