Hi! I'm a 2nd year student of EE and need help in solving this assingment.
Operational amplifier uses two reverse biased Zener diodes, calculate output voltage (in the picture 'Uiz')
I provided a circuit which should discharge at a specific time. But this circuit is not working as an oscillator. How should I make circuit which will give me oscillation?
I need to replace 1N5274B zener diode. it is rated 130V. Can I replace with other zener diode with 130V? is there any general rule to place zener diode?
