Hi,
Can anyone suggest me DC offset cancellation circuit for high frequency application (50 MHz) circuits.
I used the continuous time feedback model circuit include LPF+OTA, but it degrades the opamp gain and linearity at common mode output votlage range.
I am not sure the sampling clock based DCOC will work for high speed applications or not?
Thanks,
