Java tutorial javatpointThe objective of this lab is to familiarize you specifically with the single stage BJT common emitter (CE) amplifier and all its wonderful properties. The next lab will cover the same properties of the common base and common collector (a.k.a. emitter follower) cases. By the end of this lab and the next you will begin Coupled Amplifiers. Short introduction to small-signal analysis. Example: common base amplifier analysis. Coupled Amplifiers Part 1; Coupled Amplifiers Part 2; Spice netlist for CE-CC amplifier example. Coupled Amplifiers Part 3; Coupled Amplifiers Part 4. Current Mirrors and Differential Amplifiers. Current Mirrors and differential amplifier introduction. Most of these types of transistor amplifier applications are commonly used in RF communication and optical fiber communications (OFC). Common base configuration has a gain less than unity. In this configuration collector is connected to ground. We have low output impedance and high input impedance in common base configuration. The surprising thing about transistors is that when a base current flows (because the base-emitter junction is biased in the forward direction as above) then a collector current will also flow even though the base-collector junction is biased in the reverse direction. Also, the collector current is much larger than the base current. Start by reading the pre-lab and lab instructions in the EE 248 Lab Manual. Complete the pre-lab, BEFORE coming to lab. This portion of the lab manual is also available on the web. See EE 248 Expt 7. You will find it helpful to bring one 3.5" floppy disk to lab with you, so you can save your data and plot it out for your lab report.

Common Source (CS)– the ac input is applied at C G, the ac output is taken at C D, and C S is connected to a dc voltage source or ground. This is analogous to the common-emitter configuration for the BJT. between the base and emitter alleviates the influence of a dark current when operating at a high temperature. The circuit shown in Figure 10 (B) features a cascade connection of the grounded-base transistor (Tr1) so that the phototransistor is virtually less loaded, thereby improving the response. AMPLIFIER CIRCUIT USING TRANSISTOR Sometimes common base configuration is referred to as common base amplifier, CB amplifier, or CB configuration. The input signal is applied between the emitter and base terminals while the corresponding output signal is taken across the collector and base terminals.

In an NPN transistor, the three terminals are named the emitter (first N-block), the base (P-block), and the collector (second N-block). AMPLIFIERS – INTRODUCTION. Amplifiers are used extensively in electronic circuits to make an electronic signal bigger without affecting it in any other way. Generally we think of Amplifiers as audio amplifiers in the radios, CD players and stereo’s we use around the home.

Common-Gate Amplifier: • A current buffer takes the input current which may have a relatively small Norton resistance and replicates the current at the output port, which has a high output resistance • Input signal is applied to the source • Output is taken from the drain • To first order, current gain ≈1. A few design tips for photodiode amplifiers may be helpful: •Photodiode capacitance should be as low as possible. See Figure 1: CJ affects not only bandwidth but noise as well. This is because C J and the op amp’s feedback resistor form a noise-gain zero (feedback pole).
