Now remove CE, and re-run the Bode analysis. Construct the common emitter amplifier with active load. Figure 2. Use Vcc = +9Vdc. Construct the Front end low-pass filter with 10: 1 voltage divider. 1. Measure the Q-points of the transistors. 2. With the load resistor connected adjust the output voltage to 2Vpeak at the miodband frequency. Measure Vin and Vout and calculate the voltage gain. collector and emitter currents are approximately constant at around 170 times the base current. Use the cursors to find this range. Indicate the range on your plot. o Generate the plot and include it with your report. o This is the active region for which the transistor circuit acts like a very good amplifier. Here it has a Experiment No. 6 - BJT Amplifier Configurations. University of north carolina at charlotte. common-collector High Low High Low Low. Generally, the common-emitter and common-collector have a lower frequency bandwidth than the common-base.1.1 Distributed Amplifier with Three Amplifying Sections 3 2.1 Johnson-Giacoletto Hybrid-pi Equivalent Circuit for Common Emitter Configuration .. 7 2.2 Equivalent Circuit Used to Analyze Emitter Degeneration 8 2.3 Emitter Degeneration Absorbed Into Equivalent Circuit 10 2.A Calculation of Miller Admittance 12 Laboratory Experiment 4 Objective The goal of this lab is to compare biasing techniques for a common‐emitter amplifier using discrete components. Specifically we will compare bias stability for the fixed‐bias and four‐ resistor‐bias (4RB) configurations.

As part of this experiment, you will plot two other sets of curves, to show the Lab 7: Bipolar Junction TransistorsU.C. Davis Physics 116AINTRODUCTIONThe purpose of this lab is to measure some DC andAC characteristics of a transistor (a bipolar junctiontransistor, or BJT) in two useful circuitconfigurations, the emitter follower amplifier and thecommon emitter amplifier. In this experiment you’ll jump right in and start designing and building simple, useful amplifier circuits using that truly marvelous, tiny building-block of modern analog electronics: the . operational amplifier. Before you can begin to understand how to construct such amplifiers, you must understand Loaded Common-Emitter Amplifier. i.e. Low load impedance Þ low gain or high g m . But, high g m Þ low r e Þ low r in . Ideal amplifier has high gain, high r in , low r out . Impossible with a single stage –> multi-stage amps. Example – An Operational Amplifier. Differential Amp. Common-emitter amplifier: The input and output signals both share a connection to the emitter. Before, a small solar cell current saturated a transistor, illuminating a lamp. Knowing now that transistors can "throttle" their collector currents according to the amount of base current supplied by...EGR220 Than & Gab varying VCC (from 1V to 10V). Lab #8 Introduction and Objectives Although BJT (Bipolar Junction Transistor) has lost its polarity in IC (Integrated… For a common emitters transistor amplifier, the audio signal voltage across the collector resistance of $2 \,k\Omega$ is $2 \,V$. Suppose the current amplification factor of the transistor is $100$, the base current if base resistance is $1 \,k\Omega$ is the collector-emitter voltage, VCE, for various values of the base current, IB as shown on the circuit of Figure 6.
