Abstract

A radiation hardened by a design delay-locked loop (DLL) architecture for quadrature phase clock generation in a 133 MHz DDR memory designed on a foundry 0.13 μ m fabrication process is presented. The DLL employs an all-digital architecture, including a hardened digital integrator using error-correction logic. The area and power overhead due to the hardening are 32% and 37%, respectively. Simulation results demonstrate that the all-digital DLL is hardened against single-event transients with no timing impact due to hardening. Layout techniques to make the DLL hardened to multiple bit upsets are also presented.
