    摘要： In one embodiment, the invention can be a clock-generating circuit having one or more clock-processing circuits, each outputting a clock signal having an adjustable phase. Each clock-processing circuit comprises a divider and a divisor control circuit. Each divider divides an input clock signal by a respective divisor value and outputs a corresponding output clock signal whose period is determined by the divisor value and the period of the input clock signal. Each divider receives the respective divisor value from the corresponding divisor control circuit, wherein the divisor value is selected in order to achieve a desired frequency and phase for the corresponding output clock signal. Temporarily changing a divisor value can advance or delay the phase of the corresponding output clock signal without having to reset the divider.

    摘要： A bandgap reference circuit uses a pair of parallel loads and an op-amp driver circuit. The op-amp driver circuit uses NMOS inputs to sense voltage conditions at the loads. The configuration permits low-voltage response at low temperatures as a result of the configuration setting operating voltages above a saturation voltage. The op-amp driver provides an NMOS output, and a low-gain stage converts the NMOS output to an output corresponding to that of a conventional PMOS design.

    摘要： A set of interconnected delay stages, such as a voltage-controlled oscillator, has switch-controlled load circuitry connected to each output of each delay stage in the oscillator ring. In one embodiment, for each delay stage output, the switch-controlled load circuitry includes a switch, a transistor, and a current source. The switch is connected between the corresponding delay stage output and the transistor gate, the current source is connected between a power supply and the transistor drain, and the transistor source is connected to ground. In such a configuration, the transistor's gate-to-source capacitance can be applied to the corresponding delay stage output by closing the switch, for example, for lower-frequency operations. In addition, the output impedance of the current source decouples the capacitive load from the power supply, thereby substantially shielding the oscillator ring from noise in the power supply.

The adder (227) is connected to the phase detector (202) and the accumulator (219) for forming a second sum of the current sample and the accumulator output value. The controlled oscillator (232) receives the second sum, which is utilized for controlling the controlled oscillator (232).

    摘要： An apparatus and method for programmable lock detection and correction (PLDC) to a programmable accuracy in a digital delay-locked loop (DLL) based multiphase clock generator (MCG) is based on a DLL that utilizes a digital count to control the delay of a digitally controlled, multiple-tap delay line in its feedback path where stability of the digital count is used to qualify the determination of lock to a programmable accuracy and lock determination is based on combinatorial evaluation of the multiple phase outputs for the proper waveform relationships. The incidence of false lock corresponding to excessive delay through the delay line is addressed by a LOOPRESET signal that results in a reset of the digital count that controls the delay through the delay line. Additionally, programmability of the stability interval, the digital counter step size, and the accuracy of the lock provide control over lock acquisition time.
