Publication number: 20240039521Abstract: Techniques are described herein for phase modulation and interpolation that support high phase modulation resolution with high linearity. Embodiments receive a digital signal that uses a sequence of K-bit digital codes to encode a sequence of instantaneous phases for phase-modulating a local oscillator signal. A fractional divider divides a reference clock into N divided clock signals at equally spaced phase intervals and selects a pair of such signals based on first designated bits of the digital code. A fractional divider-calibrated delay line generates M delayed clock signals at equally spaced phase intervals between the selected pair of divided clock signals, and selects a pair of the delayed clock signals based on second designated bits of the digital code. A digital controlled edge interpolator generates a delayed local oscillator output signal by interpolating between the selected pair of delayed clock signals based on third designated bits of the digital code.Type: ApplicationFiled: August 1, 2022Publication date: February 1, 2024Inventors: Ahmed EMIRA, Mohamed Yehya Abbas Abdelgawad NADA, Faisal HUSSIEN, Mohamed ABOUDINA, Esmail BABAKRPUR NALOUSI

Patent number: 11206030Abstract: A transmitter circuit includes a phase locked loop circuit, having one or more operational characteristics indicative of an operating state of the phase locked loop circuit. The phase locked loop circuit is configured to generate a frequency signal. The transmitter circuit also includes a power amplifier configured to selectively drive an antenna with a drive signal according to the frequency signal, and a programmable delay circuit configured to controllably extend a propagation delay between the frequency signal and the drive signal of the power amplifier. The programmable delay circuit is programmed such that a first value of a particular operational characteristic of the phase locked loop circuit is substantially equal to a second value of the operational characteristic of the phase locked loop circuit. The first value is measured with the power amplifier not driving the antenna. The second value is measured with the power amplifier driving the antenna.Type: GrantFiled: November 27, 2020Date of Patent: December 21, 2021Assignee: SHENZHEN GOODIX TECHNOLOGY CO., LTD.Inventors: Ahmed Emira, Faisal Hussien, Esmail Babakrpur Nalousi
