Q. Explain Current-to-Current Amplifier ?
The circuit given in Figure is to amplify a current fed to the input of the op amp. Applying KCL at Y,
i1 + iS = io
Since i1 = - vY /R1, Equation becomes
iS - vYR1 = io
Because X is a virtual ground, vY =-iSRf . Hence Equation becomes
The current gain is then given by
Carrier Concentrations For the calculation of semiconductor electrical properties and analyzing device behavior, it is necessary to know the number of charge carrier
Q. A balanced wye-connected load with a per-phase impedance of 4 + j 3 is supplied by a 173-V, 60-Hz three-phase source. (a) Find the line current, the power factor, the tota
Thermal noise This is the most significant noise in an ampli?er. It is produced by random movements of electrons in the resistors. This is caused by the ?uctuations in the volt
