Latest Patents
One of Calvin Plett's latest patents is titled "Fractional frequency synthesis by sigma-delta modulating frequency of a reference clock." This invention includes a programmable frequency divider that receives a high-speed clock as input and provides a modulated reference clock as output. It also features a Sigma-Delta modulator that receives a Frequency Control Word (FCW) and controls the average frequency of the modulated reference clock. Additionally, an integer-N Phase Lock Loop (PLL) is incorporated to output a clock signal.
Another significant patent is the "Quarter-rate charge-steering decision feedback equalizer (DFE)." This DFE comprises four charge-steering primary latches and four primary taps, with two latches driven by complementary in-phase quarter-rate clocks and the other two by complementary quadrature quarter-rate clocks. This innovative design ensures that no element of the DFE is driven by half-rate clocks, enhancing its performance.
