摘要： A multi-mode low noise amplifier (LNA) with transformer source degeneration is described. In an exemplary design, the multi-mode LNA includes first, second, and third transistors and first and second inductors. The first transistor has its source coupled to the first inductor, amplifies an input signal, and provides a first amplified signal in a first mode. The second transistor has its source coupled to the second inductor, amplifies the input signal, and provides a second amplified signal in a second mode. The third transistor has its source coupled to the second inductor. The first and third transistors receive the input signal and conduct current through the first and second inductors, respectively, in a third mode. The first transistor observes source degeneration from a transformer formed by the first and second inductors, amplifies the input signal, and provides a third amplified signal in the third mode.

摘要： A modified derivative superposition (MDS) low noise amplifier (LNA) includes a main current path and a cancel current path. Third-order distortion in the cancel path is used to cancel third-order distortion in the main path. In one novel aspect, there is a separate source degeneration inductor for each of the two current paths, thereby facilitating tuning of one current path without affecting the other current path. In a second novel aspect, a deboost current path is provided that does not pass through the LNA load. The deboost current allows negative feedback to be increased without generating headroom problems. In a third novel aspect, the cancel current path and/or deboost current path is programmably disabled to reduce power consumption and improve noise figure in operational modes that do not require high linearity.
