Hybrid pi model
This is what I have and I was wondering where C2 might go if I make apply the hybrid pi model on this circuit. I know that all the DC Voltages should be shorted if I were to make use of an equivalent circuit, so that in the hybrid pi model R1 should be in the input and R3 in the output. But what about C2? It was already grounded from the beginning.Fig. 4 Top: Small-signal BJT cascode using hybrid-pi model Bottom: Equivalent circuit for BJT cascode using amplifier low-frequency parameters. The g-parameters found in the above formulas can be used to construct a small-signal voltage amplifier with the same gain, input and output resistance as the original cascode (an equivalent circuit). Homework Statement I'm trying to find a relation for the voltage gain of an emitter follower. For an emitter follower the voltage gain is given by...

This calculator computes the Input Resistance (Ri), Small signal output resistance (r0) and Small signal diffusion resistance (rp). The hybrid-pi model is a linearized two-port network approximation to the BJT using the small-signal base-emitter voltage and collector-emitter voltage as independent variables, and the small-signal base current and collector current as dependent variables.And this model has nothing to do with semiconductor physics. On the other hand for example the hybrid pi or T-model is highly related to semiconductor physics. Hybrid-pi/T-model is called a "physical model" because they more or less accurately reflect the "physics phenomenons" that occur inside the BJT. \$\endgroup\$ –hybrid pi model of ce amplifier |hybrid pi model of common emitter amplifier |hybrid pi model |transistor hybrid pi model |ect202 analog circuits |module 2 |...
