Abstract: Aspects of the disclosure provide a circuit having a jittered clock generator. The jittered clock generator is configured to add jitter of a controlled characteristic to a first clock signal of a clock frequency to generate a second clock signal to be used by a transceiver for operating at a radio frequency. The jitter of the controlled characteristic adjusts a clock harmonic at the radio frequency of the transceiver.

Abstract: The present invention relates to hydrogels based on hyaluronic acid based derivatives, that are more resistant than hyaluronic acid alone towards chemical and enzymatic degradation and are endowed with a mix of chemical and mechanical properties such that they are of optimal use in several surgeries, for instance for injection in bone fractures or cavities and for the production of coatings of prostheses in orthopedic surgery, as fillers in cosmetic and maxillo-facial surgery, as anti-adhesion barrier in the prevention of postoperative adhesions in abdominal and abdominal/pelvic surgery, and in general surgery. These hydrogels can be loaded with several different kinds of compounds having pharmacological and biological activity, that are then released from the hydrogel in the site of intervention.

Abstract: In one embodiment, an apparatus includes a jitter generator configured to receive a reference clock; add jitter to the reference clock; and output the reference clock with the included jitter to a phase lock loop (PLL). The PLL is used to generate a local oscillator (LO) signal for a transceiver. A jitter controller outputs a signal to the jitter generator to control a characteristic of the jitter added to the reference clock. The reference clock with the added jitter is used to reduce a fractional spur caused by a radio frequency (RF) attacker coupling into the PLL.

Abstract: Aspects of the disclosure provide a phase-locked loop (PLL). The PLL includes a voltage-controlled oscillator (VCO), a detector module, and a ramp module. The VCO has a first capacitor unit and a second capacitor unit. The VCO is configured to generate an oscillating signal having a frequency based on a first capacitance of the first capacitor unit and a second capacitance of the second capacitor unit. The detector module is configured to generate a voltage signal as a function of the oscillating signal and a reference signal. The voltage signal is used to control the first capacitor unit to stabilize the frequency of the oscillating signal. The ramp module is configured to generate a ramp signal based on the voltage signal. The ramp signal is used to control the second capacitor unit to ramp the second capacitance from a first value to a second value.
