Hello All
I have a problem in the following ct.
it's functioning right but with gain = c1/c2 , it should be 2c1/c2 since it's differential opamp
however after analyzing the waves I found that the o/p is not differential (see attached figures) due to common mode phase
attached the ct. and the wave forms . the opamp is fully differential (veriloga ) , the input is differential too.
c1/c2= 0.23.
I really don't understand this issue
