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
Design a DC motor control system to run the 48V DC motor at 40rpm up to max load of the motor. You are responsible for designing the control of a 24V supply along with the speed s
what is the working of thermal transducers?
Avalanche breakdown region: Even though these regions are well described for sufficiently large applied voltage, they overlap somewhat for small (less than a few hundred milli
Voltage Quadrupler : A voltage quadrupler circuit is shown in fig. which provides output voltage V0 = 4 Vm. Operation : Capacitor C 1 , C 2 and C 3 charges to Vm, 2Vm and 2Vm
1. Introduction: Theory: Amplitude is defined as the magnitude of the change in the oscillating variable with each oscillation within an oscillating system. It is calculated as
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,
Q. An integrator as shown in Figure is to be designed to solve dy(t) / dt + 2000y (t) = 0 with y(0) = 5. If R i is chosen to be 10 k, find C f .
