Abstract :
DC and low-frequency-noise characteristics of epitaxially grown raised-emitter (ERE) SiGe HBTs were investigated. Experimental results indicate unexpected emitter-size dependencies of both base current and low-frequency noise. An ERE SiGe HBT with a scaled emitter exhibits about 10 times smaller 1/f noise than a poly-Si emitter SiGe HBT
