Lab 12: BJT Common Emitter Amplifier 1. Objectives Study and characterize BJT amplifier in Common Emitter (CE) configuration: Determine the amplifier load line and find the DC operating point (Q-point); Measure voltage gain, cut-off frequency and input impedance; Phaco settings for beginners
characteristics to your lab report. Label βDC on the curves. The normal βDC of 2N2222 is between 100-200. Also use the information in Lab 5 BJT IV curve. 2. Common-Emitter amplifier Construct the circuit shown in Figure 1. You can use either 1 uF for capacitor C B and 4.7 uF for the capacitor C C. As the load resistance ( RL ) is connected in series with the collector, the current gain of the common emitter transistor configuration is quite large as it is the ratio of Ic/Ib. Atransistors current gain is given the Greek symbol of Beta, ( β ). values. In this experiment, transistor type 2N3904 is used. 2. Introduction: Common emitter amplifiers are the most widely used form of BJT in amplifier configurations. It is mostly used to provide reasonably high voltage gain as well as some power gain. However, another two amplifier configurations can also be used to provide some power gain, or to provide
Experiment 6 Transistors as amplifiers and switches Our final topic of the term is an introduction to the transistor as a discrete circuit element. ... Common-emitter ... COMMON EMITTER AMPLIFIER: QUIESCENT STATE The first step is to construct the bias network and check that the correct dc levels (quiescent voltages) are established. Assemble the common emitter stage as shown in Figure 7.4, but without the input and output coupling capacitors or the emitter capacitor (without C in, C out, and C E ).

LAB REPORT 012 The three types of BJT voltage amplifiers are the common-emitter, common-base, and common-collector amplifiers. The word common means that both the input and output share that particular node. The common-emitter and common-base amplifiers have voltage gain. The input signal voltage is multiplied by the gain of the amplifier at the output. Electronics Laboratory II EECS 3440 Lab Manual ... Experiment 4 JFET Common-Source Amplifier ... Report 1.

1.9. types of standards depending on the object and the standardization aspect, as well as the content of the requirements being established, the. Abstract: The Common Emitter Amplifier is one of the three basic transistor amplifier configurations. In this experiment, the student will build and investigate a basic NPN common emitter transistor amplifier. It is assumed that the student has had some background in transistor amplifier theory, including the use of ac equivalent circuits.
