Design a discrete transistor feedback current amplifier to provide a current gain of 30.
Assume the available transistors have parameters hF E = 120 and VA = ∞.
The signal current source has a source resistance of RS = 25 k Ω and the load is RL = 500 Ω.
Verify the design with a computer simulation. Determine Ri f and Rof .

An integrated circuit employs the source follower and the common-source stage shown in Fig. 9.37(a). Design a current mirror that produces I1 and I2 from a 0.3-mA reference.
3-bit Serial in, Parallel out Shift Register with asynchronous active low reset Requirement:-use rising edge D-ff(D flip flop) with asynchronous active low reset
a cnostant freqency step down chopper system us used for thecontrol of dc series motor from 550v. The armature and fieldresistances are 0.03Ω and 0.02Ω respectively, the average current in the motor circuit being 300A
What is the vertical synchronizing pulse rate?
Design the power requirements for load 3 so that the source voltage and the current drawn from the source are in phase. Draw the power triangle for load 3 and label all sides and the power factor angle with appropiate numerical values.
Using the multimeter, measure and record the actual resistance values of the resistors. Set the DC power supply to provide 15V (verify with your multimeter), and build the circuit in Figure 1 on your breadboard.
An op-amp has a single-pole, open loop response with the dc open loop gain of A0=20,000 and the pole frequency at fp=40 Hz. A. If this amplifier is connected as a non-inverting amplifier configuration with the closed loop gain
a 500-turn toroid of square cross section has an inner radius of 10cm and an outer radius of 15cm. The relative permeability of the core is 1000. For a current of 10A in the coil, calculate(a) the energy density, (b)the stored energy
Write the mathematical expressions for the current iL and the voltage vL following the closing of the switch. Note the magnitude and direction of the initial current.
A rectangular loop of wire containing a high resistance voltmeter has corners initially at (a/2, b/2, 0), (-a/2, b/2, 0), (-a/2, -b/2, 0) and (a/2,-b/2, 0). The loop begins to rotate about the x axis at constant angular velocity w.
An electric field in free space is E=(5z^2/e0)az V/m. Find the total charge contained within a cube, centered at the origin, of 4-m side length, in which all sides are parallel to coordinate axes (and therefore each side intersects an axis at +2 o..
