Latest Patents
One of Garrett's latest patents focuses on integrated circuit high voltage protection. This invention provides a solution for protecting the thin gate oxide of MOS field effect transistors from irreversible damage caused by undesired high voltages and currents. These high voltages can be generated by electrostatic discharge during handling or other circumstances. The protection mechanism consists of a two-stage circuit that effectively shunts thousands or tens of volts away from the protected transistors. The first stage employs a thick field effect transistor to guard against very high voltages, while the second stage utilizes a thin field effect transistor to protect against lower, yet still excessive, voltages. This innovative protection circuit is integrated into the chip design, surrounding the lead bonding pad connected to the transistors.
