Frequency synthesizer architecture
A frequency synthesizer is provided with a PLL, including a divider by N circuit and a phase generation circuit which is connected to the output of the VCO of the PLL. The phase generation circuit generates a predetermined number of phases synchronized on the frequency of the VCO and at intervals from each other equal to a time difference representative of a phase error measured by a phase comparator of the PLL. A signal generation circuit provides an intermediate signal starting from the phases, the period of which is dependent on the time difference and a first adjustment parameter. The intermediate signal is applied to the divider by N circuit. A correction circuit determines the phase error accumulated during N−1 periods of the intermediate signal and makes a correction of the intermediate signal every N periods of the intermediate signal as a function of the accumulated phase error such that the loop becomes stable.

Multistage analog/digital converter and method for calibrating said converter
A multistage analog/digital converter for converting in multi-step cycles an input signal into respective digital codes, each cycle step resolving at least one bit of a respective digital code. The converter includes: a sampling circuit inputting the signal and outputting a first sequence of analog samples; a generation block of a pseudorandom sequence of samples; a summing node, such as to input the first sequence and the pseudorandom sequence, obtaining in output a second sequence of analog samples including non-pseudorandom samples; a converter having a controllable digital gain receiving the second sequence and outputting bits of the digital codes; a feedback loop with a loop gain and including an analog amplifier; a digital calibration block to match the digital gain to the loop gain and including a prediction block to produce a digital estimation of said input signal starting from the bits resulting from converting the non-pseudorandom samples.

Basis of termination
From the record · verbatim“On August 18, 2023, Plaintiff dismissed all claims in this case without prejudice. (Dkt. 6). Rule 41(a)(1)(A)(i) allows a plaintiff to voluntarily dismiss an action without a court order by filing a notice of dismissal before the opposing party serves an answer or a motion for summary judgment. Fed. R. Civ. P. 41(a)(1)(A)(i). Defendant has not served an answer or motion for summary judgment. Plaintiff’s notice is therefore “self-effectuating and terminates the case in and of itself; no order or other action of the district court is required.” In re Amerijet Int’l, Inc., 785 F.3d 967, 973 (5th Cir. 2015), as revised (May 15, 2015). As nothing remains to resolve, IT IS ORDERED that the case is CLOSED.”
