Derive expressions for the threshold voltages vtl and vth

Reference no: EM131022100

Consider the bistable circuit of Fig. with the op amp's positive input terminal connected to a positive-voltage source V through a resistor R3.

(a) Derive expressions for the threshold voltages VTL and VTH in terms of the op amp's saturation levels L+ and L-, R1, R2, R3, and V.

(b) Let L+=-L- =10 V, V =15 V, and R1 = 10 kΩ. Find the values of R2 and R3 that result in VTL =+4.9 V and VTH =+5.1 V.
