Radiation Hard By Design (RHBD) Electronics

Current RHBD electronics are limited to speeds that approximate 250 MHz, regardless of the electronic process. The fact that determines the final speed is based on the nature of the current SEU (single-event upsets) radiation-tolerant latches, and the data flow between the latches through combinational...
