hello,
I want to know the resolution of your THA,and what do you mean in your article "55dB@58.125MHz",it seems that the measure is in the undersampling condition.
Do you measure the sample switch' THD? it will limit the THA performance.about the on-resistance , i think you should make it constant ,not lower.
sorry, my English is poor, i hope you can understand my ideal.
