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
part of dc machine
SUB Subtract Instruction This instruction is used to subtract the contents of any register or memory location from the contents of accumulator. There are two formats as
Q. Write a note on clampers ? Clamper is a circuit that "clamps" a signal to a different dc level. The different types of clampers are positive negative and biased clampers.
(a) Design a passive high pass filter that has a maximally flat response with a 50 Ω resistive load. Assume that the cut-off frequency is 40 kHz and that at a frequency of 25 kHz,
