Question

Question 4 (8 Marks) It is required to design a circuit (using op-amps) that can generate a square wave. i. Draw the circuit (using op-amps) that you would use to generate a square wave. (2 Marks) ii. Derive expressions for TH T , duty cycle and the frequency of the generated square wave. Clearly sketch the different waveforms in your circuit. 4 Marks) iii. Let's assume that in your design you canonly use 10k Ω resistors. Choose the values of the other circuit components in your design such that the square wave (2 Marks) has a frequency of 1e and a duty cycle of

?
ii. Derive expressions for T H, TL, duty cycle and the frequency of the generated
square wave. Clearly sketch the different waveforms in your circuit?
iii. Let’s assume that in your design you can only use 10k Ω resistors. Choose the
values of the other circuit components in your design such that the square wave
has a frequency of 1kHz , and a duty cycle of 1?
