Howe. 650-659 INTRODUCTION In this lab, you will build and analyze a differential amplifier, or "differential pair". AC analysis of JFET. Use 1% tolerance resistors and make sure that they are as well-matched as you can make them (use your digital ohmmeter if necessary). Differential amplifiers are one of the most common building blocks in analog circuit design. LAB!4:!Instrumentation!Amplifier! Instrumentation!Amplifier! Differential amplifiers are used whenever a desired signal is the difference between two signals, particularly when this difference is masked by common mode noise. The amplifier which amplifies the difference between two input signals is called as Differential amplifier. 1. Experiment 1. 6. Introduction In the previous lab, we looked at two different current sources (sinks) and compared their performance. Assemble the full circuit ... generator (just as were used the first two lab experiments). 4.

Be sure to limit the amplitude applied at the input to avoid overdriving the differential stage or saturating its output signal Lab Procedure, Part B Implement your differential amplifier designed. 1.0 Objective. UC Berkeley EE 105. To study the basics of Differential Amplifiers. The standard Differential Amplifier circuit now becomes a differential voltage comparator by “Comparing” one input voltage to the other. A major benefit of using a differential amplifier is to get rid of noise or interference signal present in the input signal. Instrumentation Lab. Department of Electrical and Computer Engineering. Experiment No 1.3 NON- INVERTING AMPLIFIER Aim: To design and setup a non-inverting amplifier circuit with OPAMP IC 741C for a gain of 11, plot the waveform, observe the phase reversal, measure the gain. The 741 contains a differential amplifier input stage. A differential amplifier is designed to give the difference between two input signals. 3. The collector and emitter resistors will be Thus the desired output from our ECG amplifier is a 5V maximum amplitude signal, with a frequency range of 0.5 to 100 Hz.

CIRCUITS LABORATORY EXPERIMENT 9 Operational Amplifiers 9.1 INTRODUCTION An operational amplifier ("op amp") is a direct-coupled, differential-input, high- gain voltage amplifier, usually packaged in the form of a small integrated circuit. The front end of every op amp, for example, consists of a differential amplifier. For this lab, the same differential amplifier design was utilized as a front­end to a “mini op amp”. Below figure shows the ideal differential amplifier. Objectives: After completion of this experiment, student will be able to design and setup a non-inverting amplifier using OP AMP. On Lab Chip 6 there is a differential pair provided (BJTDPDE) which will allow you to investigate some of the properties of emitter degenerated differential pairs. Differential amplifier. 8. It has this name because this circuit amplifies the difference between two input voltages. amplifier is taken single-ended from only one collector) and common mode gains for the new differential amplifier. INTRODUCTIONTOMICROELECTRONICCIRCUITS! Measure the DC voltages on all the nodes and calculate from them all currents in the circuit. The circuit is shown below.
