Abstract: The circuit and method translate a logic level input signal to signals at high voltage levels to drive a power device, such as a power MOSFET, while minimizing the power consumption. The circuit for driving the power device includes a low side gate driver, and a high side gate driver adjacent thereto. The high side gate drive includes a high side gate driver logic input, a high side gate driver output, a latch connected between the high side gate driver logic input and the high side gate driver output, and a control circuit receiving an output of the latch and controlling signals from the high side gate driver logic input to the latch based upon the output of the latch.

Abstract: A spatial and complementary polarity device redundancy-based analog circuit architecture mitigates against single event transients. At least one and preferably multiple redundant spatially separate copies of the complementary device-configured analog circuit (such as a voltage reference or an operational amplifier) are coupled in parallel to the circuit's output node, via a complementary polarity device path. The parallel inputs to the multiple spaced apart devices make the likelihood of a single particle passing through multiple circuits at the same time extremely remote, so that the intended value of the electrical parameter will be sustained by either the given circuit itself or any circuit copy at which the upset event does not occur.

Abstract: An analog comparator architecture has improved immunity to single event effects and variations in input offset voltage. A conventional single analog comparator-based circuit is replaced with plural comparators, driving a nullmajority votenull logic block. The effective input offset voltage of the multi-comparator design is the middle one of the individual comparators' input offset voltages. A single event upset on any comparator may momentarily perturb its output into the incorrect state; however, the output of the majority voting logic block will remain in the correct state, as only one comparator is upset. In addition, where a heavy ion strike on any comparator's bias current source causes a momentary loss of bias current, this upsets only one comparator, so that the output of the voting logic block is unaffected.

Abstract translation: 模拟比较器架构提高了对单个事件效应的抵抗力和输入失调电压的变化。 传统的基于单个模拟比较器的电路被多个比较器替代，驱动“多数投票”逻辑块。 多比较器设计的有效输入失调电压是各个比较器输入失调电压的中间值。 任何比较器上的单个事件不适应可能会暂时将其输出扰乱到不正确的状态; 然而，多数表决逻辑块的输出将保持在正确的状态，因为只有一个比较器不舒服。 此外，当任何比较器的偏置电流源发生重离子撞击时，均会导致偏置电流的瞬时损耗，因此这只会扰乱一个比较器，因此投票逻辑块的输出不受影响。
