walid Posted July 19, 2005 Report Share Posted July 19, 2005 if I have to amplify a sig of 10mV peak (20mV P-P) using a voltage divider common emitter configuration. Power supply is 9VDC. What values of RB1 & RB2 should be to maintain these two conditions:1- conserve (not waste) the battery.2- No distortion in the o/p sig.Note: please write the expression you use to solve this problem, thanks.

What values of RB1 & RB2 should be to maintain these two conditions:1- conserve (not waste) the battery.You can design a transistor circuit to use any amount of battery current you want. It all depends on the resistance of its load.2- No distortion in the o/p sig.The amount of distortion of a single common emitter transistor depends on its load resistance and its gain.Since you don't specify a load resistance nor amount of gain required then a solution is impossible. :( Quote Link to comment Share on other sites More sharing options...
