Patent ID: 7944230

Claim:
A method to prevent the propagation of a single event transient glitch from a driving logic cell to a driven logic cell, the method comprising: receiving a transient glitch at an output of a driving logic cell; generating a voltage drop across a resistive element of a resistor-capacitor (RC) differentiator circuit coupled to the output of the driving logic cell, the voltage drop generated as a result of the received transient glitch; and controlling a gate-body voltage of a depletion mode MOS device with the voltage drop generated across the resistive element, wherein the depletion mode MOS device is coupled between the output of the driving logic cell and an input to the driven logic cell, and wherein the voltage drop generated across the resistive element as a result of the transient glitch is sufficient to place the depletion mode MOS device in cut-off, thereby disconnecting the driving logic cell from the driven logic cell to prevent the propagation of the transient glitch.
