Hi,could someone confirm someone could confirm whether my analysis of this circuit that implements an or gate with cmos is correct?
I find it a little confusing that the output is extracted from that point.
For the output to be equal to 1(high state) Q5 will always have to be on,right?
I mean is not possible the output to be 1 if Q5 is off and Q6 is on rigth?
Input A Input B
0 0
Q1 ON,Q2 OFF,Q3 OFF,Q4 OFF,Q5 OFF ,Q6 ON
Output = 0
Input A Input B
0 1
Q1 ON,Q2 ON,Q3 OFF,Q4 ON,Q5 ON ,Q6 ON
Output = 1
Input A Input B
1 0
Q1 OFF,Q2 OFF,Q3 OFF,Q4 ON,Q5 OFF ,Q6 OFF
Output = 0 (this is not correct ,since this is a or gate.The state of Q5 will determine wheater the ouput is 1 or 0.Q5 depends on the state of Q2 and Q3.So if Q2 is off and Q3 is ON this means that Q5 will be on?It is not necessary that Q2 is ON in order to Q5 be on to?
Input A Input B
1 0
Output = 0 -->same situation as for the previous situation
Q1 OFF,Q2 OFF,Q3 O3 ON,Q4 ON,Q5 OFF ,Q6 OFF
Thanks
