Abstract

To meet the requirements of both high reliability and low power in low-orbit aerospace applications, this article first presents a single-event Double-Upset (SEDU) self-Recoverable and single-event Transient (SET) Pulse Filterable (DURTPF) latch design with low power. The DURTPF latch mainly consists of eight mutually feeding-back C-elements (CEs) and an SET pulse filterable Schmitt-trigger (ST). To make an ST behave not only as a pulse filterable ST but also as an error interceptive CE, an input-split ST is created, leading to an enhanced-version of the DURTPF latch, namely DURTPF-EV. The DURTPF-EV latch mainly consists of seven mutually feeding-back CEs including an input-split ST. Simulation results demonstrate both the SEDU self-recoverability and SET pulse filterability of the proposed latches at the cost of moderate silicon area. Using the clock gating technology, the DURTPF latch reduces power dissipation by about 63% on average compared with the state-of-the-art SEDU self-recoverable latch designs that are not SET-pulse filterable. Moreover, the DURTPF-EV latch is more cost-effective and its reliability is also enhanced, making it more suitable for low power and low-orbit aerospace applications.
