BJT Common-Emitter Amplifier 🎯 Midband Gain, Low-Frequency & High-Frequency Cutoff 👉 FULL DETAILS💡

In this video, we take a detailed look at the frequency response analysis of a BJT Common-Emitter Amplifier using an NPN transistor. The circuit includes four capacitors: 🔹Input coupling capacitor (C1) 🔹Output coupling capacitor (C2) 🔹Emitter bypass capacitor (CE) 🔹Load capacitor (CL) 💡 To structure the discussion clearly, the content is divided into four main parts: ▶️ PART 1 – DC Analysis: We calculate all required DC operating points (bias voltages and currents), which are essential for building the small-signal model in the next step. ▶️ PART 2 – AC Analysis & Midband Voltage Gain: We develop the small-signal model and calculate the midband voltage gain of the amplifier using standard AC analysis techniques. ▶️ PART 3 – Low-Frequency Cutoff (SCTC Method): Using the Short-Circuit Time Constant (SCTC) method, we evaluate the lower cutoff frequency by analyzing the time constants associated with C1, C2, and CE. ▶️ PART 4 – High-Frequency Cutoff (OCTC Method): We apply the Open-Circuit Time Constant (OCTC) method to determine the upper cutoff frequency, considering the parasitic capacitances of the BJT (Cπ and Cu) and the load capacitor CL. 👉 What You'll Learn: ✅ How to determine the DC values and how they affect the AC response ✅ How to model the amplifier using the small-signal equivalent circuit ✅ How to calculate the midband voltage gain of the amplifier ✅ How to use the Short-Circuit Time Constant (SCTC) method ✅ How to use the Open-Circuit Time Constant (OCTC) method ✅ How the output coupling capacitor introduces a highpass filter behavior ✅ How to determine the cutoff (corner) frequencies (lower and upper cutoff) 🎯 Step-by-Step Analysis: 🔹 DC Analysis 🔹 AC Small-Signal Model – Replace the BJT with its equivalent circuit 🔹 Frequency Response – Effect of the capacitors on voltage gain and cutoff frequency 🔹 Voltage Gain – Calculations using small-signal parameters 🔹 Lower Cutoff Frequency Calculation – Based on Short-Circuit Time Constant (SCTC) Method 🔹 Upper Cutoff Frequency Calculation – Based on Open-Circuit Time Constant (OCTC) Method 🧪 Verification: All calculations are verified using TINA-TI SPICE simulations for accuracy and practical insights. 💡 Perfect for: Engineering students, electronics hobbyists, and anyone learning analog circuit design. 🎯 Outline: ⏩ 00:00:00 Introduction ⏩ 00:00:27 Outline Discussion ⏩ 00:00:51 PART 1: DC Analysis Calculations ⏩ 00:06:05 PART 1: DC Simulation Results TINA-TI SPICE ⏩ 00:07:35 PART 2: Small-Signal Model for Voltage Gain ⏩ 00:12:26 PART 3: AC Analysis for Lower Cutoff ⏩ 00:20:09 PART 4: AC Analysis for Upper Cutoff ⏩ 00:41:50 Bode Plot Simulation Results TINA-TI SPICE 👉 Playlist Transistor Circuits:    • Transistor Circuits   👉 Playlist Analog Electronics:    • Analog Electronics   ⭐ If you have questions or comments, please let me know.
