S Recall that: • If a closed-loop (CL) system is stable, then one may increase the gain (by up to a certain amount) and still maintain CL stability. . On the other hand, if the CL system in unstable, then one may decrease the gain (by up to a certain amount) and still have CL instability. You find that the gain margin of a nominal loop transfer function (with no right-half plane open-loop pole) to be -40 dB.

The open-loop gain A of real (nonideal) op-amps isvery large at low frequencies but decreases markedlyas frequency increases. As a result, the closed-loopgain of op-amp circuits can be strongly dependent on frequency. Determine the relationship between a finiteand frequency-dependent open-loop gain AV(OL)(ω)and the closed-loop gain AV(CL)(ω) of an invertingamplifier as a function of frequency. Plot AV(CL)versus ω. Notice that −RF/RS is the low-frequencyclosed-loop gain.
To overcome the false output transitions of simple comparators, Schmitt trigger circuits utilising positive feedback are utilised. For such as circuit, shown in Fig.Q.A2c, derive what would be the values of the upper threshold point (UTP or Vt + ), lower threshold point (LTP or Vt - ) as a function of the voltage divider circuit and the saturation values (+Vsat, -Vsat) associated with the op-amp. Please provide a clear rationale for the steps in derivation of the relationship. A Schmitt trigger circuit is required to have saturation values ±12 V, and a switching thresholds of ±3 V. For the Schmitt trigger circuit shown in Figure Q.A2c, determine the values of Rx and Ry such that the above-mentioned conditions are fulfilled. Also, sketch the input-output characteristic of such an inverting Schmitt-trigger. Clearly label axes, the threshold voltages and the saturation voltages in your sketch.
