Abstract:
1. A method of calibrating a device, said method comprising: assessing said device, said device comprising cross-coupled transistors requiring a balanced state when said cross-coupled transistors are initialized to a same predetermined voltage and said assessing being performed to determine a current preferred state towards which said device is skewed away from said balanced state when said cross-coupled transistors are initialized to said same predetermined voltage, wherein said current preferred state is one of a first state and a second state opposite said first state; initiating a burn-in process with said device in a selected one of said first state and said second state and with said cross-coupled transistors initialized to said same predetermined voltage such that, during said burn-in process, said device is fatigued away from said current preferred state towards said balanced state; and during said burn-in process, repeatedly reassessing said device to determine if said current preferred state has changed and, if said current preferred state has changed, switching said device to an opposite state from said selected one of said first state and said second state.
