Abstract:
A computer system having a component dependent on a clock signal, comprising:first circuitry that generates a transition on a first signal dependent on whether the clock signal is active; and second circuitry that generates a transition on a clock detect indication signal dependent on the first signal, comprising: a first capacitor coupled to a first node, wherein current flows along one of a first current path and a second current path dependent on the transition on the first signal, wherein the first current path is defined as a path from the first node to ground, and wherein the second current path is defined as a path from a power supply to the first node, wherein the first capacitor is charged and the first node is discharged when current flows along the first current path, and wherein the first capacitor is discharged and the first node is charged when current flows along the second current path.
