Dear All~!
Thanks in advance.
I designed DA with cascode structure.(see the attached file)
In two tone test, IM3 is 32dBc@4dBm(output power) (CMOS 0.18um, Vdd:1.8V)
I need IM3 >40dBc.
I think the DA is the well-known structure and many people use it.
Do you know the method that improve linearity?
Please let me know the method and related materials.
