    Darlington TR

    Hi audioguru We have two formulas 1=Cin(miller)=Cbc(Av(mid)+1) 2=Cout(miller)=Cbc((Av+1)/Av) Can i use these formulas in high frequency Thanks

    Darlington TR

    HI audioguru With VceQ of only 0.5V then the transistor can't do anything useful. Its power dissipation is only 0.5mW (not 5mW) if you need it to operate at such a low power. i mean

    Darlington TR

    Hi  audioguru I know that every transistor has its own specfications but today i saw the book of electronic devices by Robert .T. paynter in which he designed the common emitter amplifier by transistor 2N3904 he take VCC=10 and ICQ=1ma and in his design he told that datasheet of 2N3904 gives...

    HI audioguru i have a question that indata sheet of any transistor these values are given Ic=10ma,VCE=10V HFEmin=100,HFEmax=300. so these Ic  and VCE are saturation values    OR    quiescent values Thanks

    Darlington TR

    Hi audioguru Another problem occure that input  and output are not out of phase image shows this clearly and when i removed bypass and increase  the frequency  the out put is no longer sine wave image shows

    Darlington TR

    Hi audioguru sorry I worngly write cross instead of gross i reduced the gross over distortion by introducing negative feedback I replace the 100uF bypass capacitor with 1.5uF and  I m attaching Two images first with distortion and second with reduced distortion and show me how much distortion...
