## maxsteel 3 years ago Lab 3 Your goal for this lab is to design a circuit that implements a 3-input logic gate that implements Z=¬(C(A+B)) where the ¬ symbol stands for logical negation. This function is enumerated in the following truth table: C B A | Z ========= 0 0 0 | 1 0 0 1 | 1 0 1 0 | 1 0 1 1 | 1 1 0 0 | 1 1 0 1 | 0 1 1 0 | 0 1 1 1 | 0 The schematic diagram below includes the resistive pullup for the logic gate and some voltage sources that serve as the power supply and generators for the signals that will be the inputs to the gate. The voltage sources generate the three input signals (A,

The question is not complete.

That's the diagram for the implementation of the output Z.

What I kind of understand is that you have to draw the circuit of Z in the grid given to complete the circuit.

But since, I don't do this course I can't be sure of my answer.

However, about the combinational circuit given in the attachments I'm sure It's good...!! :) But if that's really what you are required too in the question...That's where 1 have doubts..!! :) Sorry for not being of more help..!! :) Good Luck for your work..!! :)

use map method to solve it ans is A' +B'C'

how to design a mosfet

Sorry but I'm a first year student in this course and we only started 4 weeks ago.. So i don't really know what's a mosfet..!! But if you are not in a hurry for the labsheet You could go to http://www.allexperts.com/el/Electronics/ and post your question..!! For sure, he'll have the answer..!!

Sorry again for not being of much help..!! :)

mosfet for what?

12. maxsteel

the question clearly stated to design a mosfet such that the output is exact as giveb below

change the w/L ratio to change the Ron. The tutorials help a lot to solve the problem. U can see them to know how to calculate the Ron. so that u get the o/p correctly.
