Consider the bistable circuit of Fig. 18.22(a) with the op amps negative-input terminal
Chapter 18, Problem 18.33(choose chapter or problem)
Consider the bistable circuit of Fig. 18.22(a) with the op amps 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 amps saturation levels L+ and L, R1, R2, and VR. (b) Let L+ = L = V and R1 = 10 k. Find R2 and VR that result in threshold voltages of 0 and V/10.
