发明名称 Multi-junction semiconductor circuit and method
摘要 Aspects of the present disclosure are directed to methods, apparatuses and systems involving a multi junction semiconductor circuit. According to an example embodiment, an apparatus includes a multi junction semiconductor circuit including a first current path and a second current path, each current path having respective first and second common voltage nodes to provide an output that is proportional to absolute temperature. The first current path includes a first p-n junction exhibiting a first current density. The second current path includes a second p-n junction exhibiting a second current density that is proportionally different than the first current density, and a resistor connected between the second p-n junction and the second common voltage node. Further, the apparatus includes a current-tap path connected to a node between the resistor and the second p-n junction, the current-tap path diverts a portion of current that flows through the resistor away from the second p-n junction.
