The Gain Bandwidth Product is found to be = ANALOG AND DIGITAL CIRCUITS LAB MANUAL/ III rd SEM/ ECE Page 12 4. DIFFERENTIAL AMPLIFIER USING BJT Aim: To construct a differential amplifier using BJT and to determine the dc collector current of individual transistors. Output Signal Cadmium Sulfide Differential Amplifier Simple Circuit Difference Amplifier These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves. THEORY: An operational amplifier (or an op-amp) is an integrated circuit (IC) that operates as a voltage amplifier. An op-amp has a differential input. That is, it has two inputs of opposite polarity. An op-amp has a single output and a very high gain, which means that the output signal is much higher than input signal. The two input terminals.
EE ELECTRONICS I LABORATORY. EXPERIMENT 7 LAB MANUAL. MOSFET AMPLIFIER DESIGN AND ANALYSIS. OBJECTIVES. In this experiment you will • Learn procedures for working with static-sensitive devices. • Construct constant-current sources, active loads and amplifiers using only enhancement-mode MOSFETS. The FET Differential Amplifier Basic Circuit Fig. 1 shows the circuit diagram of a MOSFET differential amplifier. The tail supply is modeled as a current source I0 Q having a parallel resistance RQ. In the case of an ideal current source, RQ is an open circuit. Often a diffamp is designed with a resistive tail supply. In this case, I0 Q=0. PSPICE LAB MANUAL ECE-BEC 21 AIM: To verify the characteristics of CS Amplifier So far we have looked at the bipolar type transistor amplifier and especially the common emitter amplifier, but small signal amplifiers can also be made using Field Effect Transistors or FET's for short.
Data collected during this laboratory experiment will be compared to the datasheet of the operational amplifier used. References: The following two links are to. Also measure the DC values of drain voltages for M1 and M2 and compare them with calculated values. 3. Calculate the common-mode voltage gain from the. As will be demonstrated in a later experiment,. the common base amplifier is also used in conjunction with FET amplifiers for high. frequency amplification.
