Digitally Augmented Analog Phase Locked Loop with Accurate Bandwidth (18023585)

Inventor Henrik Sjöland

Brief explanation

This abstract describes the use of digital circuitry in an analog Phase-Locked Loop (PLL) to calibrate and maintain the bandwidth of the PLL. The digital calibration circuit adjusts the value of a resistor or capacitor in the loop filter to achieve a desired RC product. A digital control circuit reads time-to-digital converters (TDC) that measure the length of pulses from the phase-frequency detector (PFD) to the charge pump (CP) during a frequency change. These pulse lengths are added together to determine the integral CP current. The control circuit then calculates the integral CP current needed to achieve the desired bandwidth, taking into account the VCO tuning sensitivity based on the calibrated RC product. The CP current is adjusted accordingly by the ratio of the calculated integral CP current to the measured integral CP current. The digital circuits are only activated initially and occasionally to compensate for temperature changes or significant frequency shifts. They do not increase power consumption or affect normal PLL operation.

Abstract

An analog PLL employs digital circuitry for calibration and characterization, precisely setting and maintaining the bandwidth of the PLL. A digital calibration circuit calibrates the value of the resistor or capacitor in the loop filter to yield a desired RC product. A digital control circuit reads time-to-digital converters (TDC) digitizing the length of the CU and CD pulses from the phase-frequency detector (PFD) to the charge pump (CP) during a frequency change. These pulse lengths are summed to yield a measured integral CP current. The control circuit determines an integral CP current that yields a desired bandwidth, regardless of the VCO tuning sensitivity, based on the calibrated RC product. The CP current is then adjusted by the ratio of determined integral CP current to the measured integral CP current. The digital circuits are only activate initially, and occasionally to compensate for temperature drift or upon a significant frequency change. Since they are not used during normal PLL operation, the digital circuits do not increase power consumption or adversely affect system operation.

Inventor Christine Jost

Brief explanation

The abstract describes a method used by network equipment in a wireless communication network to ensure the integrity of messages. The network equipment obtains integrity verification information from a portion of the message and digitally signs an assertion that includes this information.

Network equipment implements a network function in a wireless communication network. The network equipment obtains integrity verification information that is a function of only a portion of a message. The message is either a request for a service to be consumed by the network function or a response to a request for a service provided by the network function. The network equipment digitally signs an assertion that includes the integrity verification information, and then sends the message and the digitally signed assertion to a service communication proxy. Other network equipment that receives the message and the digitally signed assertion may check an integrity of the portion of the message, based on integrity verification information that the other network equipment obtains and on the integrity verification information included in the digitally signed assertion.

Inventor Jonas Sedin

Brief explanation

The abstract describes a wireless device (AP1) that wants to access a communication medium. Once it gains access, it reserves a specific time period called TXOP on the medium.
