摘要： A determination is made if a temperature of a system has exceeded a hot threshold or a cold threshold. At room temperature, a first adjustment is determined for first nominal settings. The first nominal settings are for a first input to a first comparator. At room temperature, a second adjustment is determined for second nominal settings. The second nominal settings are for a first input to a second comparator. The temperature is monitored, during normal operation of the system, using a temperature dependent voltage with the first comparator adjusted with the first adjustment and second comparator adjusted with the second adjustment.

摘要： Signal edge alignment embodiments include multiple delay stages connected in series. Each delay stage includes a delay line, an interface circuit, and a tap selection circuit. The delay line applies fixed-width delays to an input signal to produce delayed versions of the input signal at a plurality of taps. The interface circuit, which is characterized by an inherent interface circuit delay, passes one of the delayed versions to an interface circuit output in response to a control signal. The tap selection circuit determines a finally-identified tap of the plurality of taps by determining an initially-identified tap at which a delayed version of the input signal most closely has a desired alignment with the input signal, and by identifying the finally-identified tap in the control signal as a tap that occurs earlier in the delay line than the initially-identified tap. This compensates for the inherent delay of the delay stage.

摘要： Apparatus are provided for a voltage-controlled oscillator module. A voltage-controlled oscillator module comprises an input node for receiving an input voltage, a voltage-controlled oscillator, and voltage translation circuitry coupled between the input node and the voltage-controlled oscillator. The voltage translation circuitry is configured to generate a control voltage based on the input voltage and the voltage-controlled oscillator generates an oscillating signal at an oscillation frequency in response to the control voltage. Biasing circuitry is coupled to the voltage translation circuitry, and the biasing circuitry is configured to adjust the ratio of the control voltage to the input voltage.

摘要： A logic circuit including at least one evaluate circuit coupled to a static output logic circuit. In one example, the evaluate circuit includes a dynamic node, a full keeper, an evaluate device, and a logic tree. In some examples, the output logic circuit is a sampled static output logic circuit and includes a sample device. In some examples, the logic circuit includes multiple evaluate circuits, each with a dynamic node coupled to a control gate of a transistor of the output logic circuit. Some examples may include a delay in a clock signal to increase the internal race margin.
