Latest Patents

Kashif Sheikh holds a patent for a "Fractional-N frequency synthesizer having reduced fractional switching noise." This invention provides a solution for reducing fractional switching noise and spurious signals in frequency synthesizers. The synthesizer includes a voltage-controlled oscillator that generates an output signal. A fractional-N divider responds to this oscillator, producing a divided output signal that contains fractional switching noise. A band-pass filter is employed to mitigate this noise and the non-linearities that lead to spurious signals. Additionally, a phase detector compares a reference signal with the output from the band-pass filter, generating a control signal that reflects the phase difference. A loop filter then processes this control signal to effectively manage the voltage-controlled oscillator, resulting in reduced noise and spurious signals.
