WebDec 8, 2024 · In a good HBT such as one using AlGaAs for an emitter and GaAs for a base, ΔE g ≈ 0.2eV. At room temperature k b T= 0.025eV and ΔE g / k b T = 8. Therefore ΔE g / k b T ≈ 3000. In a typical HBT, N e /P b ≈ 1/10. That is, the base is heavily doped compared to the emitter, minimizing base width modulation. WebException to color bands: In military equipments extra color band (Reliability band) on resistors specifies failure rate (in %) per 1000 Hrs of service. The failure rate for different colors is, Brown – 1%, Red – 0.1%, Orange – 0.01%, Yellow – 0.001%. Resistor having only single black band is called as zero-ohm resistor.
