EXPERIMENT 6 TRANSISTOR CHARACTERISTICS 6.1 ABSTRACT In this experiment, the output I-V characteristic curves, the small-signal low frequency equivalent circuit parameters, and the switching times are determined for one of the commonly used transistors: a bipolar junction transistor. CRO Operation and its Measurements 9. APPARATUS: 1-D.C power supply . Now the collector voltage is increased by adjusting the rheostat Rh 2. The circuit diagram for studying drain and transfer characteristics is shown in the figure1. THEORY The acronym ‘FET’ stands for field effect transistor. Familiarity with basic characteristics and parameters of the J-FET. Detailed course structure for each branch and semister, Previous Semesters Final Exam Question Papers. PRELAB . It is relatively immune to radiation. Why the common-source (CS) amplifier may be viewed as a transconductance amplifier or as a voltage amplifier? 6. … CHARACTERISTICS OF JFETS. For applications like low noise, these types of transistors are preferred. Experiment No.12 Field Effect Transistor (FET) OBJECT: To investigate the FET characteristics . From experiment, we can state that this voltage starts approximately at 8 V and the drain current approaches 10.5 mA. Why an input characteristic of FET is not drawn? Wir zeigen euch drei Anleitungen für Experimente mit Fett. Output Small Signal Characteristics Experiment-Part1 In this part, we will measure the NMOS threshold voltage. While doing the experiment do not exceed the … When gate to source voltage V GS is … 2-Oscilloscope ,A.V.Ometer . 2. For analog switching, the FET is preferred. We will use the IC CD4007. 2. The base current I B is kept constant (eg. By keeping the base current (I B) constant, collector- emitter (V CE) voltage is varied and the corresponding I C values are obtained. JFET Characteristics and the Transconductance Model The JFET gate and drain-source form a pn junction diode; a very simple model of the JFET is shown at right. BJT-CE Amplifier 10. Experiments 8 • Experiment 1 10 Study of the characteristics of JFET (Junction field effect transistor) in common source configuration and evaluation of: 4. There are two types of static characteristics viz (1) Output or drain characteristic and (2) Transfer characteristic. Kontextabhängigkeit und Generalisierbarkeit. 20µA) by adjusting the rheostat Rh 1. Plot the IV- characteristics for voltages (measured over the diode) between - 5V and 0.6 V. To avoid tripping the fuse in the multimeter it is better to use it as a voltmeter in parallel to the resistor and calculate the current than to use it in series in the circuit. Output characteristics. Ans:    Where  IDS is the saturation drain current, IDSS is the value of IDS when VGS=0, and VP is the pinch -off voltage. 5. N-Channel junction field effect transistor characteristics laboratory experiment using the 2N5457 through 2N5459 series general purpose JFET. Ans: The common source amplifier gain is A v = -g m R D . PRELAB. UJT Characteristics 8. OBJECTIVE In this lab, you will study the I-V characteristics and small-signal model of a Metal Oxide Semiconductor Field Effect Transistor (MOSFET).
