A technique for reinitializing a coupled circuit, the technique including receiving a common configuration value associated with states of a coupled circuit, tracking states associated with the coupled circuit while the coupled circuit is in a low power state based on the common configuration value, receiving the tracked state associated with the coupled circuit, receiving a scaling value associated with the coupled circuit, determining a current state of the coupled circuit based on the tracked state and the scaling value, and transmitting an indication of the current state to the coupled circuit when the coupled circuit has exited the low power state.

Low power digital modes for duty-cycled integrated transceivers

Dual mode filters having two reconfigurable multi-stage filters. In a dual band mode, each reconfigurable filter filters an input signal in a different band using every filter stage. In a single band mode, both reconfigurable filters are effectively divided into two sub-chains that include either the odd-numbered filter stages or the even-numbered filter stages. Together, the four sub-chains in the single band mode filter an input signal in a single band with a higher parallelization than each reconfigurable filter in the dual band mode. In some embodiments, the dual mode filter is a decimation filter. In other embodiments, the dual mode filter is a resampling filter. In still other embodiments, the dual mode filter is an interpolation filter.

Dual mode digital filters for RF sampling transceivers

An integrated circuit comprises an input, a digital step attenuator, an analog-to-digital converter, a first output, a second output, a first bandwidth filter, a first band attack detector, a first band decay detector, a second bandwidth filter, a second band attack detector, a second band decay detector, and an automatic gain control. The ADC is configured to output a digital signal including a first and a second frequency range. The first and second bandwidth filters are configured to extract respective digital signals comprising the first and second frequency ranges. The band attack and decay detectors are configured to detect band peaks or decays thereof such that the DSA and External AMP may be controlled by means of the AGC based on the detected band peaks or decays, and ADC attack and ADC decay.
