Your equation should read ## I_E=I_B (\beta+1) ##. Try again. I think you also need to assume ## V_{BE}=.7 \, volts ## (approximately). One hint for you: The capacitors basically block any steady state current trying to go through them so the capacitor is an open circuit for the DC part of the analysis.adamaero said:
A BJT (Bipolar Junction Transistor) circuit is a type of electronic circuit that uses bipolar junction transistors as its main component. It is a three-layer semiconductor device that can amplify and switch electronic signals.
Analog circuits use continuous, varying signals to represent data, whereas digital circuits use discrete signals with only two possible states (on or off) to represent data. Analog circuits are better suited for processing and amplifying audio and video signals, while digital circuits are more efficient for processing and storing data.
To analyze a BJT circuit, you can use Kirchhoff's circuit laws and the BJT's current-voltage characteristics. First, apply Kirchhoff's laws to determine the current and voltage values at different points in the circuit. Then, use the BJT's characteristics (such as the base-emitter voltage and collector current relationship) to calculate the values of the BJT's parameters, such as its current gain and output resistance.
BJT amplifiers are used to increase the strength of an electronic signal. They can amplify both alternating current (AC) and direct current (DC) signals by controlling the amount of current flowing through the device. BJT amplifiers are commonly used in audio and radio frequency (RF) applications.
BJT circuits have a wide range of applications in electronics, including amplifiers, switches, oscillators, and logic gates. They are commonly used in audio and video equipment, power supplies, and communication systems. BJT circuits are also used in computer processors and other digital devices as a component of logic gates and memory cells.
