Hi All,
Im new to this site and putting my first query i hope i can get a quick solution to my problem .
I am a professional "FPGA circuit porter",we make a circuit in which 74164 is given 16 times the frequency to pin 8.The op generated and given to 8 resistors 120k,47k,30k,22k,22k,30k,47k,120k wth one of their legs shorted.This output is given to LM324 pin 3 with a resistor.Thus generating a sine wave of fixed frequency.
But when im replacing the op of 74164 with FPGA ,the offset of the op of LM324 is not 0V.
Please suggest any ideas.
Regards,
Abhishek
