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
Q. An interface circuit consisting of R 1 and R 2 is designed between the source and the load, as illustrated in Figure such that the load sees a Thevenin resistance of 50 betw
Usage: Because of the above inherent drawbacks, fixed bias is seldom used in linear circuits (that is those circuits which use the transistor like a current source). Instead,
whether piezo crystal and quazt crystal oscillator are same?
Consider a simple zener voltage regulator with the circuit diagram shown in Figure (a). (a) For a small reverse resistance R Z S and V S - R S i out > V Z , show that v ou
An n-channel depletion MOSFET, for which I DSS = 7mA and V P = 4 V, is said to be operating in the ohmic region with drain current i D = 1 mA when v DS = 0.8 V. Neglecting the
Q. Given that V 0 = 10 V, determine IS in the circuit drawn in Figure.
Q. An integrator with positive voltage on a noninverting input is shown in Figure. Sketch v o for 60 ms after S has been opened.
A 300 km, 3-phase, 50Hz transmission line has spacing as shown in Figure. Each phase of the line consists of a bundle of three conductors. (a) Find the total per-phase inductanc
