Abstract
An SRAM delay circuit that tracks bitcell characteristics. A circuit is disclosed that includes an input node for receiving an input signal; a reference node for capturing a reference current from a plurality of reference cells; a capacitance network having a discharge that is controlled by the reference current; and an output circuit that outputs the input signal with a delay, wherein the delay is controlled by the discharge of the capacitance network.
