Hi,
I am running SINAD simulation for my switched cap filter. The acceptable lower limit is 25 dB. I am getting value close to that. Even with ideal amplifier it is not improving much.
So I am just trying to check SINAD for transmission gates used for switching the capacitor. So now in the test bench I have four switches and a capacitor (that is euivalent a resistor) and a capacitor, i.e , so a low pass filter basically. But this simple configuration gives me SINAD less than 25 dB. And I have tried differnt input signal magnitude.
Could someone give me advice how can I improve the SINAD of transmission gate.
Thanks and Regards,
Prasanta
