A receiver in an impulse wireless communication. The method includes providing a metal gate, an etch stop layer formed on the MG, and a dielectric layer formed on the ESL. The first plunger is disposed such that an end thereof is capable of extending into a main cap recess and the second plunger is disposed such that an end thereof is capable of extending into an auxiliary cap recess. Before implementing a rate change, signals from multiple sensors are cross-checked.
