Abstract
Embodiments described herein provide a method for correcting a propagation delay induced error in an output of an asynchronous counter. An input clock is applied to the asynchronous counter. A gray-code count is generated by the asynchronous counter. The gray-code count is mapped to a binary count. An error component, indicative of a counting error induced by a propagation delay between the input clock and the binary count, is generated by taking an exclusive-OR operation over the gray-code count and the input clock. The error component is added to the binary count to generate an error-corrected binary count. The error-corrected binary count is output.
