15.40 Consider the bistable circuit of Fig. 15.22(a) with the op amp’s negative-input terminal disconnected from ground and connected to a reference voltage VR. (a) Derive expressions for the threshold voltages VTL and VTH in terms of the op amp’s saturation levels L+ and L−, R1, R2, and VR. (b) Let L+ = −L− = V and R1 = 10 kΩ. Find R2 and VR that result in threshold voltages of 0 and V/10.
