Dear all,
I am doing the matching work for differential LNA around 2GHz. To save the chip area, the input matching network is depended on the off-chip components, such as inductor and capacitor. But one thing makes me confused: since there will be discrepancies between off-chip components due to the process. These discrepancies will lead to the matching imbalance for differential LNA,such as amplitude differential. Could you give me some suggestions to reduce the matching imbalance?
best regards,
