<p>The thermal voltage ($V_T$) in semiconductor diodes is given by $V_T = \frac{kT}{q}$, where $k$ is the Boltzmann constant, $T$ is the temperature in Kelvin, and $q$ is the elementary charge. It represents the voltage equivalent to the thermal energy at a given temperature and plays a crucial role in determining the diode current-voltage characteristics.</p> Signup and view all the answers

<p>The different biasing configurations for bipolar junction transistors include fixed bias, emitter-stabilized bias, and voltage-divider bias. The equations for these configurations are: fixed bias - $I_B = \frac{V_{CC} - V_{BE}}{R_B}$, emitter-stabilized bias - $I_B = \frac{V_{CC} - V_{BE}}{R_B + (\beta + 1)R_E}$, voltage-divider bias - $R_{Th} = R_1 || R_2$, $E_{Th} = E$. These configurations are used to establish the operating point of the transistor.</p> Signup and view all the answers
