Abstract: Aspects of this disclosure relate to reducing settling time of a ramp signal in a phase-locked loop. An offset signal can be applied to adjust an input signal provided to an integrator of a loop filter of the phase-locked loop to cause the settling time to be reduced. Disclosed methods of reducing settling time of a ramp signal can improve settling time of a ramp signal independent of the profile of the ramp signal.

Abstract: A phase-locked loop (PLL) comprising a multi-band oscillator and a memory configured to store control input for the oscillator. The PLL is operable in a calibration mode in which the PLL is configured to acquire a frequency controlled word (FCW) for the PLL corresponding to a frequency generated by the oscillator in response to a first control input threshold on a first band of the oscillator; generate a frequency corresponding to said FCW on a second band of the oscillator adjacent to said first band; identify a second control input causing the oscillator to generate said frequency corresponding to said FCW and store said second control input in memory.

Abstract: Apparatus and methods for synchronization of multiple semiconductor dies are provided herein. In certain implementations, a reference clock signal is distributed to two or more semiconductor dies that each include at least one data converter. The two or more dies include a master die that generates a data converter synchronization signal, and at least one slave die that processes the data converter synchronization signal to align timing of data conversion operations across the dies, for instance, to obtain a high degree of timing coherence for digital sampling. In certain implementations, the dies correspond to radar chips of a radar system, and the data converter synchronization signal corresponds to an analog-to-digital converter (ADC) synchronization signal. Additionally, the master radar chip generates a ramp synchronization signal to synchronize transmission sequencing across the radar chips and/or to provide phase alignment of ADC clock signals.

Abstract: The present invention describes a new peptide aldehyde produced naturally by Streptomyces lividans 66, which we have called livipeptin. Using genome mining of natural products, we predicted that SLI0883-5 genes encode an unprecedented biosynthetic system, unusually small (4.6 Kbp), which produces an acylated peptide aldehyde. Because of the chemical characteristics of the predicted compound, we postulated its anti-proteolytic activity, which we confirmed by identifying and purifying this compound through metabolic profiles of HPLC and MS of the mutated strain lacking these three genes and the wild strain. To this objective, we identified the conditions wherein these genes are strongly expressed. The livipeptin was purified and its inhibitory activity on the proteolytic activity of selected proteases was demonstrated in vitro. The design of an expression cassette for its heterologous expression is also described plus its use for heterologous protein production.

Abstract: Aspects of this disclosure relate to reducing settling time of a sawtooth ramp signal in a phase-locked loop. Information from a loop filter of the phase-locked loop can be stored and used within the loop filter so as to improve the settling time of the sawtooth ramp signal. In certain embodiments, the settling time of a periodic sawtooth ramp signal can be reduced to less than one microsecond. An output frequency at the end of the sawtooth chirp can be brought back to an initial value without significantly modifying phase error in disclosed embodiments.

Abstract: A chip includes a phase-locked loop (PLL) and a test controller. The PLL includes an oscillator and a phase detector. In a normal mode, a first feedback loop includes a phase detector and an oscillator that generates an output based on a frequency input signal. In a test mode, the PLL is re-configured. The output of the loop filter can be decoupled from the input of the oscillator in the test mode and instead be coupled to the input of the phase detector. The oscillator can receive a test tuning signal provided by the test controller. In this test mode configuration, the PLL can measure the frequency of the oscillator.
