High efficiency power amplifier design using GaAs HFETs The correlation between W-CDMA ACPRs and HFET intermodulation distortions was discussed. Characterization of a double-doped power HJFET for W-CDMA cellular handset application Another possibility that is being pursued is the utilization of digital...
As is the case with hFE for transistors, the current transfer ratio is an important parameter for transistor-output photocouplers. The value of this current transfer ratio has temperature Ta, LED current IF, and transistor collector-emitter voltage VCE dependencies. In addition, when an LED is ...
aThe CTR depends upon the current gain (hfe) of the transistor, the supply voltage to the phototransistor, the forward current through the IRED and operating temperature. CTR取决于晶体管、 () 电源电压对光电晶体管,向前潮流通过IRED和操作温度的电流增益hfe。[translate] ...
What is re equal to in terms of h-parameters? The h-parameters of a transistor used in a common emitter circuit are hie = 1.0 KΩ, hre = 1.0 x 10-4, hfe = 50 and hoe = 100 µmhos. The load resistor for the transistor is 1KΩ in the collector circuit. The transistor is supp...
When you check datasheets you will find that theβdcof a transistor being represented as thehFE. In this term the letterhis inspired from the word hybrid as in transistorhybrid equivalent ac circuit, I will elucidate more on this in our upcoming articles. The subscriptsFin (hFE) is extracted...

Probably tweaking R1 to give symmetrical clipping (Q1 goes into cutoff at the low swing, same when it goes into clipping on the high swing) is what's missing in the waveforms as shown. Simulation tends to overestimate hFE, and your bias levels may simply be lower than expected from simulat...
