Abstract :
A technique to build overlapped inductors at the same location while keeping good isolation between them is presented. The key idea is to use magnetic and electric cancellation to reduce coupling. A shared LNA for WiFi and Bluetooth (BT) applications using the overlapped inductor is proposed. It enables independent gain control up to the first RF stage in a receiver so that the system integration complexity is reduced.
