Question

i)draw the transafer charcheristics for this circuit?

Question 4 (11 Marks) Consider the given Bistable Multivibrator circuit (to the right). i. Draw the transfer characteristics (i.e. vo vs. v, ) for this circuit. Ri R2 (1 Mark) ii. Derive expressions for VIH and Vm in terms of R,R, L and L.F O vo iii. Let L. 10 V, and R=1k0,choose R, în orderto get a hysteresis of 100mV width iv. An engineer decided to modify the given circuit by disconnecting the inverting input of the op-amp from the ground and connecting it to a constant voltage source v .Derive expressions for VH and V in terms of R,R, L',L, and V . Draw the transfer characteristics in this case. (3 Mark) tramsfeu chas or vi and rz intena a.valage

ii)Derive expressions for VTH and VTL?

iii)Let L+ = - L- = 10 V, and R1=1 k Ω , choose R2 in order to get a hysteresis of
