Systems, devices and methods are disclosed for an ultra-wide-band (UWB) transmitter tag capable of operating in different power mode depending on voltage level and/or host interruption signal. The transmitter tag comprises a power management circuit, a one-time-programmable memory (OTP), a read/write memory, a state machine for controlling/monitoring the operation of the tag. The tag goes into the high power mode when the power supply ramps up to a preset voltage level. During the high power mode, the tag consumes the higher level of electrical current as indicated by the battery current signal. Upon completion of high power consumption activity, such as OTP memory download, the tag exits the high power mode and enters the low power mode. The power supply current goes to the low level to minimize the power consumption by the tag.

Low power ultra-wide-band transmitter

Embodiments of the present invention include methods and systems for detecting a peak of an ultra-wide-band (UWB) signal in a data stream. The system () for detecting a peak of an ultra-wide-band (UWB) signal () in a data stream () includes: one or more processors (); and a non-transitory computer-readable medium or media () comprising one or more sequences of instructions which, when executed by the one or more processors (), causes steps to be performed comprising: selecting a portion () of a data stream () in a current clock cycle, the portion () of the data stream includes a preset number of data samples; finding a set of data samples included in the preset number of data samples, the set of data samples includes one or more consecutive data samples and has a uniform magnitude; and promoting the set of data samples as a peak if the uniform magnitude is higher than a magnitude of a first data sample that immediately precedes the set of data samples and a magnitude of a second data sample that immediately follows the set of data samples.

Peak detection in data stream

A FFT module for a baseband processor of a receiver includes an input for receiving a timing window correction signal. In response to the timing window correction signal the FFT module adjusts a timing window for processing groups of samples within an input queue of the FFT module.

Apparatus, system, and method for sample timing synchronization in a receiver

An apparatus, system, and method are described for synchronously resetting logic circuits. A synchronous reset signal is coupled to at least one asynchronous reset input for synchronously resetting sequential logic. In one embodiment, reset logic generates a signal coupled to the at least one asynchronous reset input of the sequential logic to synchronously reset the sequential logic.
