WebDesigning a high voltage gain amplifier: So let us start designing for the circuit shown in figure 1. We pick the transistor BC109, as it is having hfe around 300. We assume Vbe as 0.7 V for a typical forward biased junction. Hence VRb = 5 – 0.7V = 4.3 V.

Web8 de fev. de 2015 · The intrinsic emitter resistance is: re= (1/gm)*hfe/ (hfe+1), with hfe=hFE (Ic). In a sense, the emitter resistance (as given by re=Vt/Ic) is "adjusted" to account for the fact that some base current flows. Based on your comment, at first I thought this might affect voltage gain, but no, it doesn't. WebThe MoS2–HZO ferroelectric FETs (FeFETs) have exhibited excellent performance including ferroelectric polarization switching with a high on/off ratio and negligible degradation in endurance and retention properties. Our results shown here suggest that MoS2–HZO FeFETs can be a promising alternative for next-generation nonvolatile …
