BJT Cascode Amplifier Calculator

BJT Cascode Amplifier Calculator

Calculate the approximate voltage gain of a BJT cascode amplifier.

The gain is approximated by:
For an ideal cascode amplifier: \[ g_m = \frac{I_C}{V_T}, \quad A_v \approx -g_m \times R_C \]
where \(V_T\) is assumed to be 25 mV.

Step 1: Enter Amplifier Parameters

Example: 1 mA

Example: 10,000 Ω (10 kΩ)

Formulas:
\( g_m = \dfrac{I_C}{V_T} \) with \( V_T = 25\,\text{mV} \)
\( A_v \approx -g_m \times R_C \)
