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. Web7 de dez. de 2011 · Single transistors (i. e. without internal darlington topology) with very high hfe up to 3000 are not often to find. Here some examples: NEC 2SC3616

Web9 de out. de 2012 · So high hfe increases output impedance up to the point where hfe exceeds gm RE; beyond that diminishing returns set in. If we assume one diode drop across the emitter resistor then gm RE will be around thirty so we want hfe to be greater than thirty to optimise the circuit.
