A feedback interference cancellation circuit is presented that uses a control loop to reject blockers in wireless receivers. The concept is based on a feedback translational loop which subtracts a blocker replica from the original blocker signal. In

An LNA with integrated Q-enhanced notch filter for use in FDD transceiver systems has been demonstrated. The amplifier core is coilless, made possible by the use of capacitive shunt-series feedback to simplify matching. Additionally, a Q-enhanced not
