Typical junction trans. beta is in the range of 10 to several hundreds. Alpha is the ratio of collector to its emitter current, Alpha = Ic/Ie.DC gain is -R2/R1 and AC gain reduces to -3dB when ZC (f)=R2. – Tony Stewart EE75. May 22, 2021 at 15:27. Your formula with time-derivatives is in the 'time domain' (signals are described as varying in time). Transfer functions (or coefficients if you prefer that term) are in the 'frequency domain' (signal amplitudes are a function of …The forward current transfer ratio h fe can similarly be defined in terms of ac quantities, or as the ratio of dc current changes. In both cases, the output voltage (V CE) must be held constant. Equation 6-8 can be used to determine h fe from the CE current gain characteristics. Figure 6-15 shows the measurement of ΔI C and ΔI B at one point on the …The current transfer ratio (CTR), leakage current, propagation delay, rise time and fall time of the LTCC-based high-temperature optocouplers are measured over a range of temperatures from 25 to ....
