Latest Patents

Sushil Kumar holds a patent for a "Spread spectrum controllable delay clock buffer with zero cycle slip." This invention features a controllable delay clock buffer that provides spread spectrum modulation of output signals without any cycle slip. The design incorporates a phase-locked loop (PLL) with a loop filter that includes an RC network. A clock signal is input to the PLL, and a spread spectrum modulation frequency is injected into the capacitor of the PLL loop filter. The secondary charge pump generates a programmable waveform, which is integrated by the loop filter capacitor to create a corresponding triangular or trigonal waveform. This waveform modulates the input to the voltage-controlled oscillator (VCO) of the PLL, defining a frequency modulation profile with a triangular or trigonal envelope. The bandpass profile of the spread spectrum modulation signal operates at a higher frequency than the lowpass profile of the PLL, ensuring that the waveform profile remains undistorted.
