SUMMARY

The discussion focuses on designing a circuit using diodes, resistors, and zener diodes to achieve a specific voltage output. The goal is to ensure that the output voltage (Vout) remains zero when the input voltage (Vin) is below 3.6V and equals Vin minus 3.6V when Vin exceeds 3.6V. Participants emphasize the importance of understanding zener diodes to effectively implement this design, especially for managing the transition point at 3.6V.

PREREQUISITES
  • Understanding of diode behavior, specifically pn junction diodes
  • Knowledge of zener diode operation and its voltage regulation capabilities
  • Familiarity with basic circuit design principles involving resistors
  • Ability to analyze voltage levels in electronic circuits
NEXT STEPS
  • Research zener diode voltage regulation techniques
  • Learn about designing circuits with diodes for voltage clamping
  • Explore half-wave rectifier circuits and their applications
  • Study resistor voltage divider circuits to understand output voltage control
USEFUL FOR

Electronics students, circuit designers, and hobbyists interested in voltage regulation and diode applications in circuit design.

It says using diodes, resistors, and zener diodes only, design a circuit whose output remains zero for vin<3.6V, but equals vin minus a drop of 3.6V for vin>3.6V. and the circuit has to work when the input voltages are below 0 as well as above 0. and help is appreciated.

Ok. So what have you got so far? That's the problem you were given, but we're not going to do your homework FOR you. What specific question do you have?
 
I have just been thinking what i can do, I have thought that maybe having Vin and next to Vin connecting a pn junction diode so that any point before the turn on voltage, Vout would equal 0. (trying to get the idea from the half wave rectifier.)

but don't know how to get the 3.6 value as my point of change. I don't know if i am going in the right direction
 
From what you are writing, it sounds like you need to read some more about zeners.
