Abstract
Methods and circuits for detecting variations in signal propagation rates within an electronic device, and for adjusting the output timing of the device in response to the variations in signal propagation rates. According to an embodiment of the invention, a signal may be propagated through an uncompensated delay chain and a compensated delay chain. If the signal passes through the compensated chain slower than through the uncompensated delay chain, then the device may delay a clock signal such that the output timing of the device will remain within the specification parameters. In contrast, if the signal passes through the uncompensated delay chain slower than through the compensated delay chain, the device may not delay the received clock signal such that the output timing of the device will remain within specification parameters.
