Abstract
In one embodiment, a WCDMA FDD system includes an embedded filter that provides a complex load to transistors in a low noise amplifier. The complex load can be constructed using passive and/or active devices and creates an arbitrary transfer function that supports selective Q-enhancement of poles or zeros. One particular implementation of the embedded filter is in the form of an LC tank circuit. The LC tank circuit is operably coupled to the output of the low noise amplifier and creates a transfer function whose poles and zeros can be selected to reject transmitter leakage in the WCDMA system, while maintain a desirable gain at the frequency of operation.
