Abstract
A power amplifier (PA) using switched-bulk biasing to minimize the risk of output stage snapback effect is disclosed. An adaptive biasing of the output stage prevents device breakdown while accommodating large voltage swings. These protection techniques can be applied to all types of cascode configurations of a PA, including single-ended, differential, quadrature, segmented and any combination thereto.
