It is primarily a sigh gain differential amplifier which amplifies the difference tot voltages been two inputs. Below figure shows the ideal differential amplifier. 7. 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. Davis Physics 116A Reference: Bobrow, pp. 6. The current is quite small in the 741; the worst-case input bias current in the 741 is 500nA. The amplifier which amplifies the difference between two input signals is called as Differential amplifier. The 741 contains a differential amplifier input stage. This lab will introduce the student to frequency response of differential pairs. The dc bias schematic of a BJT differential amplifier is shown below. Lab Procedure, Part B Implement your differential amplifier designed. Introduction In the previous lab, we looked at two different current sources (sinks) and compared their performance.

Experiment #4 Report: Op-Amps: Integrator, Differentiator, and Follower 1. An ideal differential amplifier ignores all common-mode voltage, which is whatever level of voltage common to both inputs. Differential amplifiers are used whenever a desired signal is the difference between two signals, particularly when this difference is masked by common mode noise. Frequency response of JFET. The differential amplifier configuration is very much popular and it is used in variety of analog circuits. LEAVE THIS CIRCUIT ON YOUR BREADBOARD AS YOU NEED TO USE IT IN NEXT WEEK’S LAB EXPERIMENT. 5. The standard Differential Amplifier circuit now becomes a differential voltage comparator by “Comparing” one input voltage to the other. One way of increasing the input and output impedance of a bipolar differential pair is to degenerate the emitter of Q 1 and Q 2. ELG 3136 Lab Experiment #2 Differential Amplifiers . To do so, the three circuits below were built and measured using a custom source-measure unit and then also simulated in LTspice XVII. Differential Amplifier is the basic input stage of every op-amp.
