System and method for a dynamic voltage controlled oscillator

摘要

A system and method are provided for generating an adaptive clock signal, configured to track prevailing operating conditions within an integrated circuit. The method comprises transmitting a first signal edge to a row of cells within a memory instance, waiting for two or more selected cells within the row of cells to propagate corresponding responses based on the first signal edge, and generating a memory delay signature signal edge based on the corresponding responses. The adaptive clock signal is generated based on the delay signature signal edge.

1. A method, comprising:
transmitting a first signal to a memory delay structure included in a digital voltage controlled oscillator (DVCO), wherein the memory delay structure comprises an array of memory cells configured to model signal propagation through other instances of arrays of memory cells included in a particular clock domain; selecting a row of memory cells within the array of memory cells; sensing a plurality of column signals associated with the selected row of memory cells; and generating a memory delay signature signal based on the plurality of column signals, wherein the memory delay signature signal is configured to indicate a longest propagation delay through the selected row of memory cells.
