Table 2

Comparison between extracted and calculated breakdown noise spectral density at  V and  V for different sized SiGe HBTs.

	from calculation (×10^−22 A^2 s)	from presented noise model (×10^−22 A^2 s)
0.2 μm × 1.7 μm	0.72/0.62	0.69–0.74/0.60–0.65
0.6 μm × 1.7 μm	0.80/0.70	0.78–0.84/0.67–0.73
0.2 μm × 10.2 μm	0.85/0.71	0.83–0.89/0.69–0.74
0.6 μm × 10.2 μm	0.92/0.75	0.90–0.95/0.73–0.77
