Question

Practice [25%] The circuit shown left below is a waveform generation circuit, which consists of an integrator and a bistable multi-vibrator. The triangle symbol represents a unity-gain inverting amplifier such that V1 -v3 . R1-3k1, R2-2kQ, R3-1 ka, and C 0.1μF. The opamps are ideal except that they saturate at +10V and-10V. Be careful that the opamp in the bistable multi-vibrator is configured in a positive feedback way (a) On your answer book, sketch the output (v2) versus the input (v) for the bistable multi-vibrator. 8. in your plot, mark the transition voltages and the width of hysteresis, if any. (5%) (b) The initial parts of the waveforms for v,2, v3 and v are given in the right graph below. On your answer book, extend these waveforms to show three cycles of them. (9%) (c) Find the period of vs(8%) (d) Draw an opamp-based circuit to realize the unity-gain inverting amplifier. (396) Volt Bistable multi-vibrator 10VV2 V3
