Latest Patents

One of Shahriary's latest patents is a phase-locked loop frequency tracking device, which includes a direct digital synthesizer. This invention provides tuning over a very large bandwidth, making it suitable for wideband carrier tracking and clock recovery systems. In the first embodiment, a DC signal is formed that represents the phase difference between an input signal and a return signal. This DC signal is then applied to a narrow band voltage-controlled oscillator, which converts it back to an AC signal. The AC signal is level shifted to create a clocking pulse for an accumulator of a direct digital synthesizer. A digital command word is also applied to the accumulator, representing a coarse tuning of the input frequency, while the clocking pulse supplies fine tuning. In a second embodiment, the DC representative phase signal is applied to an analog-to-digital converter, producing an N-bit word that represents the phase difference. This innovation allows for very wideband tracking with a single phase-locked loop, thereby reducing hardware requirements and costs.
