(ii) The operational-amplifier (op-amp) of the inverting Schmitt-trigger in Figure Q.A2(e) has saturation voltages of +Vsat = +11 V and -Vsat = -11 V. The voltage divider circuit has the relationship of Rx = 2RY with the value of RY being 100 kn. Using the relationships derived above: (a) Calculate the values of the upper threshold point (UTP or Vi*), lower threshold point (LTP or Vr). (b) Now, sketch the input-output characteristic of the inverting Schmitt- trigger. Clearly label axes, the threshold voltages and the saturation voltages in your sketch.

2. Suppose we have an op-amp that is powered by a ±15 V supply (assume Vout max is ±14V), and has a maximum output current of 50 mA. The maximum slew rate of the op amp is 107 V/s. In the circuit below where Vin=5sin(100t). a. What would the output voltage Vout be if the op amp were ideal? b. Compute and draw the actual output voltage if a load resistor of Rload=100 N is attached to Vout. Vin ww 1 ΚΩ ww 4 ΚΩ + +15V Op-Amp -15V Vout

Answer the following questions a) What assumption do we make for an ideal op - amp? b) Explain what slew rate is why it is important characteristic for an op amp.
