The gate voltage of the first CMOS inverter (518, 520) is the input voltage and the gate voltage of the second CMOS inverter (522, 524) is at the reference voltage. The output voltage (516) is at the drains of the first CMOS inverter. The pMOS and nMOS current mirrors provide active loads to the first and second CMOS inverters. The sense amplifier is self-biasing by connecting the gate of the source pMOSFET to the gates of the pMOS current mirror and by connecting the gate of the sink nMOSFET to the gates of the nMOS current mirror.

    Abstract: Apparatuses, systems, and a method for providing a PLL architecture with scalable power are described. In one embodiment, a system includes one or more processing units having a voltage regulator to generate a controllably adjustable supply voltage for a phase-locked loop (PLL) circuit coupled to the voltage regulator. The PLL circuit compares a phase and frequency of the reference clock signal to a phase and frequency of a generated feedback clock signal and generates an output signal based on the comparison. A tracking unit adjusts the controllably adjustable supply voltage based on an operating frequency of the system.

    Abstract: A skew measure circuit (108), an exclusion circuit, and an up/down counter (116) are connected to form a skew detection circuit. The skew measure circuit (108) asserts a first output signal if a first input clock leads a second input clock, and asserts a second output signal if the second clock leads the first clock. The exclusion circuit (112) provides first and second digital pulse signals that represent the outputs of the skew measure circuit. The exclusion circuit also prevents the states of these pulse signals from changing, so long as the skew measure cicuit is experiencing metastability. The up/down counter's count is incremented in response to the first pulse signal and decremented in response to the other pulse signal.
