    摘要: A circuit includes multiple doped regions in a substrate. A first of the doped regions has a tip proximate to a second of the doped regions and is separated from the second doped region by an intrinsic region to form a P-I-N structure. The circuit also includes first and second electrodes electrically coupled to the first and second doped regions, respectively. The electrodes are configured to supply voltages to the first and second doped regions to reverse bias the P-I-N structure and generate light. The first doped region could include multiple tips, the second doped region could include multiple tips, and each tip of the first doped region could be proximate to one of the tips of the second doped region to form multiple P-I-N structures. The P-I-N structure could also be configured to operate in double avalanche injection conductivity mode with internal positive feedback.

    摘要: A diode for alternating current (DIAC) electrostatic discharge (ESD) protection circuit is formed in a silicon germanium (SiGe) hetrojunction bipolar transistor (HBT) process that utilizes a very thin collector region. ESD protection for a pair of to-be-protected pads is provided by utilizing the base structures and the emitter structures of the SiGe transistors.
