Abstract :
The authors present calculations of the equivalent input noise current spectral density in both tuned and untuned front-ends employing InP/InGaAs heterostructure bipolar transistors (HBTs) and identify the dominant transistor-related components of the noise. The receiver sensitivity will depend ultimately on the front-end noise. Results are presented for receivers based on InP/InGaAs HBTs as used in either 1 GB/s or 10 GB/s demonstration units. The small-signal parameters for these transistors are shown
