Abstract
In some embodiments, a power amplification system can comprise a current source configured to provide a bias current, a current mirror configured to mirror the bias current, a comparator configured to compare the mirrored bias current to a threshold current, and a transistor at an output of the comparator. The transistor can be configured to be activated in response to the mirrored bias current exceeding the threshold current.
