Testing RF circuits with true non-intrusive built-in sensors
(IEEE, 2012)
Text en actes de congrés
Accés restringit per política de l'editorialWe present a set of sensors that enable a builtin test in RF circuits. The key characteristic of these sensors is that they are non-intrusive, that is, they are not electrically connected to the RF circuit, and, thereby, ... -
