Abstract
A power amplification system comprises a current source configured to provide a bias current, a current mirror configured to mirror the bias current, and a comparator configured to compare the mirrored bias current to a threshold current and, in response to the mirrored bias current exceeding the threshold current, cause a reduction of output power.
