Abstract: Techniques for calculating a real power delivered to a transmit load of a transceiver. In an aspect, two distinct voltages are sampled from a matching network coupling the transmit load to an amplifier output. The voltages are coupled by configurable coupling elements to the down-conversion mixers of the transceiver, and are subsequently converted to digital form for processing by a baseband processor. The baseband processor may calculate a coefficient relating the calculated real power to an actual power delivered to the load. The coefficient may be stored and subsequently applied to a transmit element during normal signal transmission by the transceiver. Note the coupling elements may be configured to decouple the sampled voltages from the down-conversion mixers during normal signal reception by the transceiver, thus avoiding unnecessary loading on the receive signal path.

Abstract: A CMOS distributed amplifier with distributed active input balun is disclosed. Each gm cell within the distributed amplifier employs dual-output two-stage topology that improves gain and linearity without adversely affecting bandwidth and power.

Abstract: Described herein are code-modulated multi-signal systems. In one embodiment, a multi-signal system receives multiple input signals and code-modulates each input signal with a unique code to distinguish the input signal from the other input signals. The input signals may come from multiple antennas, multiple sensors, multiple channels, etc. The code-modulated signals are then combined into a combined signal that is sent through shared blocks and/or transmitted across a shared medium in a shared path. After shared processing and/or shared transmission, the individual signals are recovered using matched filters. Each matched filter contains a code corresponding to one of the unique codes for recovering the corresponding signal from the combined signal. The recovered signals may then be inputted to additional processors for further processing.

Abstract: Described herein are multi-band LNAs that reuse inductors for different frequency bands to minimize chip area. In an embodiment, a multi-band LNA is capable of operating in a narrowband (NB) and a wideband (WB) while reusing at least one input impedance matching inductor and at least one load inductor for both bands. The reuse of inductors results in a more efficient use of chip area. In an exemplary embodiment, the LNA comprises a common source transistor and a common gate transistor. In this embodiment, the LNA operates in a common source configuration using the common source transistor to amplify input signals in the NB, and operates in a common gate configuration using the common gate transistor to amplify input signals in the WB. The LNA reuses an input impedance matching inductor and a load inductor in both configurations, and thus both bands.
