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.
