The op amp in the circuit of Fig. has an open-loop gain of 105 and a single-pole roll off with ω3dB = 10 rad/s.
(a) Sketch a Bode plot for the loop gain.
(b) Find the frequency at which |Aβ| = 1, and find the corresponding phase margin.
(c) Find the closed-loop transfer function, including its zero and poles. Sketch a pole-zero plot. Sketch the magnitude of the transfer function versus frequency, and label the important parameters on your sketch.
Compare the results of this model to those of the model without agent breaks. Use the "Station" and "Route" modules to help you in the animation. Use the "Variable" icon to monitor and identify the metrics requested.
1) There is a delay in time between the contraction of the atria and the contraction of the ventricles. This is called the AV-delay. What structural characteristics (identify more than one!) of the conducting fibers between the AV node and AV bundle ..
Assuming α?1, neglecting ro, and assuming the current source to be ideal, derive an expression for the small-signal voltage gain A(s) ≡ Vo/Vsig that applies in the mid band and the low-frequency band. Hence find the midland gain AM and the lower 3..

The quarter circle gate BC in Fig. is hinged at C. Find the horizontal force P required to hold the gate stationary. The width b into the paper is 3 m.
TheCMOSopampof Fig. 13.1 is fabricated in a process for which V1An = 25 V/μm and/ V1 Ap /= 20 V/μm. Find A1, A2 and Av if all devices are 0.3 μm long, Q1 and Q2 are operated at overdrive voltages of 0.15-V magnitude, andQ6 is operated at VOV =0.2 ..
Discuss why phasor analysis can only be performed on single-frequency circuits. For multiple frequencies what type of analysis must be performed?
For the column decoder shown in Fig. 16.26, how many column-address bits are needed in a 1-Mbit-square array? How many NMOS pass transistors are needed in the multiplexer? How many NMOS transistors are needed in the NOR decoder? How many PMOS tran..
Describe the potential negative impacts on a small river downstream from where it receives a factory liquid waste discharge that has a high biological oxygen demand (BOD), as well as high nitrate and phosphate levels
A closed container is partially filled with water. Initially, the air above the water is at atmospheric pressure (1.01 x 1(1' Pa) and the gauge pressure at the bottom of the water is 2500 Pa. Then additional air is pumped in, increasing the press..
Design the folded-cascode circuit of Fig. to provide voltage gain of 80 dB and a unity-gain frequency of 20 MHz when CL = 10 pF. Design for IB = I, and operate all devices at the same / VOV / Utilize transistors with 1-μm channel length for which..
Knowing that the system is in equilibrium when bar AB is vertical and that collar A is given a small displacement and released, determine the period of the resultingvibrations.
