Latest Patents

Morteza Alavi holds a patent for a PLL circuit and method for generating a modulated carrier signal. This invention features a digitally controlled oscillator (DCO) that generates the modulated signal. The PLL circuit receives a desired phase change as a modulation signal at each cycle of a non-uniform clock, which is derived from the DCO output and a uniform reference clock. The phase change adjusts the DCO's frequency, while a frequency control word represents the ratio of the desired carrier frequency to the reference clock frequency. The circuit accumulates the phase change and frequency control word to predict the DCO's output phase. Additionally, a non-uniform clock compensation circuit calculates a compensation value for the phase change, and a phase detector estimates the error between the predicted phase and the time offset between the reference clock and DCO output, generating a control signal for the DCO based on this error.
