what is better to choose Ge,GaAs,Si diode to implement logic circuit ? explain why?
Homework Answers
Germanium(Ge) diode is better than the remaining given for implementing logic circuits.
- Germanium diodes have the advantage of an intrinsically low forward voltage drop, typically 0.3 volts. This low voltage drop results in low power loss and more efficient diode. Silicon diode have 0.7volts forward voltage drop while GaAs has even more.
- In low level logic circuits, the low voltage drop across a diode is very important.
- As a result Germanium diodes are more often used in low level logic circuits.

This problem is again about anti-windup logic. . Explain, in your own words, what anti-windup logic is and why is it used. Do you need to implement anti-windup logic if the actuator does not have saturation? Do you need anti-windup if there is no integral action in the controller? Do you need anti-windup if the plant has an integrator?
