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
function of a commutator in a DC motor
Q. J and K are the external inputs to the JKFF shown in Figure. Note that gates 1 and 2 are enabled only when the clock pulse is high. Consider the four cases of operation and expl
