摘要： Behaviors of a transistor during a dose rate event can be modeled using a circuit simulation software package. A subcircuit model replaces a transistor in a circuit design to be simulated. The subcircuit model can be in the form of a schematic-based representation or a netlist. The subcircuit model provides a model of a source junction and a drain junction in the transistor during the dose rate event. The subcircuit model also includes the size of the transistor being replaced and the dose rate of the dose rate event. Once the transistor is replaced with the subcircuit model, a dose rate simulation may be performed to determine the dose rate hardness of the circuit design.

摘要： A radiation hardened memory element includes at least two delay elements for maintaining radiation hardness. In an example, the memory element is an SRAM cell. Both delays are coupled together in series so that if either one of the delays fails, a delay will still be maintained within the SRAM cell. The critical areas of the delays may be positioned so that a common line of sight cannot be made between each delay and a circuit node.

摘要： A Static Random Access Memory (SRAM) having a split write control is described. The SRAM includes bit, write, and write-word lines. Each memory cell within the SRAM includes a delay which is coupled to a dedicated write-word line. When a cell is not being written, its delay receives a delay signal on its associated write-word line, which increases the response time of the cell. When a cell is to be written, however, its delay receives a bypass signal on its associated write-word line, which decreases the response time of the SRAM cell.

摘要： The disclosure describes an antenna protection circuit for use in circuits where Single Event Transients from energetic particles is a concern. The antenna protection circuit may include at least three diodes, connected electrically in series and arranged such that at most all but one of the at least three diodes produce a transient current pulse from an energetic particle. During the transient current pulse event, the remaining diode remains reverse biased thereby sufficiently blocking the transient current pulse and an SET does not occur on the signal node. The antenna protection circuit may be constructed so that no unshorted parasitic p-n junction structure is associated with any of the diodes in the circuit, which would otherwise have to be explicitly included in the at least three diodes.

摘要： A voltage divider circuit can be realized by dividing a higher than rated operating voltage across a plurality of MOS transistors. The voltage divider circuit can be used for a wide variety of ratios of low and high operating voltages. Only one gate input voltage is needed, minimizing power dissipation, heat, and hot carrier effects. The voltage divider circuit is employed in a voltage driver circuit to generate a high output voltage in response to a low voltage input while minimizing damage to the MOS transistors within the voltage driver circuit.
