  • Non-aligned antenna effect protection circuit with single event transient hardness
    Patent number: 8217458
    Abstract: 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.
