hi while designing I to V converter with 4mA to 20 mA converted to 0 to 5 V , i used inverting operational amplifier based I to V converter with feedback resistor= 300 ohm. this will give me -1.99V to -5.264V now for getting 0 to 5 V I used another non-inverting operational amplifier adder ckt...

In case of csacading of two stage of amplifier max. power should be transferred from one stage to another. now here it is recommended that input impedance of stage must be high while output impedance should be low . now my question is that is there any loading of stages and what abt max. power...

following links expalin the maximum power transfer theorem in detail http://en.wikipedia.org/wiki/Maximum_power_theorem" http://www.allaboutcircuits.com/vol_1/chpt_10/12.html"

Multistage amplifiers are made up of single transistor amplifiers connected in cascade. The first stage usually provides a high input impedance to minimize loading the source (transducer). The middle stages usually account for most of the desired voltage gain. The final state provides a low...

Maxmimum Power Transfer Theorem Help me in understanding the cascading of amplifier without loading effect.

In electrical engineering, the maximum power (transfer) theorem states that, to obtain maximum power from a source with a fixed internal resistance, the resistance of the load must be made the same as that of the source. when Rs=RL then only maximum power transfer takes place. Rs= Source...

hi i have one quiry related to input & output impedance of any circuit? generally for cascading we expect High Input impedance & Low output impedance to avod loading effect? But what is loading effect ? exactly what happen to current & voltage when loading ouucures ? how this theory...
