    摘要: A putting accuracy training aid providing an elongated, flat rolling surface and a non-slip base. A recessed tee supports a ball forward of an adjustable stroke gauge and elastomer limit stop. Inclined surfaces, projections and/or grooves provided adjacent the tee facilitate re-teeing without stooping. Jointed multi-section constructions are also disclosed having a sectional body and/or wing attachments.

    摘要: In described embodiments, a receiver includes a clock and data recovery (CDR) circuit with a voltage control oscillator (VCO) having proportional and integral loop control, and a Lock to Reference (L2R) mode circuit using Phase and Frequency Detector (PFD) control of the VCO during the absence of input data to the CDR. A regular CDR second order loop incorporating PFD control of the VCO during the absence of input data to the CDR achieves relatively rapid lock to reference when compared to counter-based lock to reference mode of operation.

    摘要: An integrated circuit input buffer is provided, which includes a differential buffer, first and second average value circuits and a feedback amplifier. The input buffer is selectively operable in a differential operating mode and a single-ended operating mode. The differential amplifier has first and second buffer inputs and first and second buffer outputs. The first and second average value circuits have inputs coupled to the first and second buffer outputs, respectively. The feedback amplifier has first and second differential inputs coupled to outputs of the first and second average value circuits, respectively, and has an amplifier output. The amplifier output is coupled to the second buffer input when the input buffer is in the single-ended operating mode and is decoupled from the second buffer input when the input buffer is in the differential operating mode.
