Patents by Inventor Doug Counce

Doug Counce has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Oscillation based access time measurement
    Patent number: 6909301
    Abstract: An embodiment of the invention is a method for measuring access time where the frequency of a ring oscillator is measured with and without a device under test 1 in the ring. Those two frequencies are compared to calculate the access time of the device under test 1. Another embodiment of the invention is circuitry 25 that measures the frequency of a ring oscillator with and without a device under test 1. Again the two frequencies are compared to calculate the access time of the device under test 1.
    Type: Grant

  • Oscillation based cycle time measurement
    Patent number: 6734743
    Abstract: An embodiment of the invention is circuitry 25 that contains a programmable delay 8 and a pulse generator 16 that send clock signals of a certain frequency to a device under test 1. The programmable delay 8 increases the frequency of the clock signal to the device under test 1 until the device under test fails. The cycle time measurement of the device under test 1 is the period of maximum frequency at which the device under test 1 operates properly.
