Robert James Landers 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).

  • Patent number: 9692446
    Abstract: An integrated circuit (IC) chip containing a Delta-Sigma (??) filter module for a ?? analog-to-digital converter and a method of providing analog to digital conversion are disclosed. The IC chip includes a ?? filter that is connected to receive a digital data stream created by a ?? modulator, provide a multibit data value when a counter reaches a selected number of received bits, and reset the counter responsive to receiving a synchronization pulse. The IC chip also includes a FIFO buffer connected to store the multibit data value only when a synchronization flag is on and to send an interrupt towards a processing unit only after storing a selected number of multibit data values. The IC chip further includes a synchronization module connected to turn on the synchronization flag responsive to receiving the synchronization pulse and to turn off the synchronization flag responsive to the sending of the interrupt.

  • Publication number: 20080163013
    Abstract: Methods, circuits and systems are provided for testing random-access memory (RAM) devices. In one embodiment, one or more test vectors are written to a RAM device. Bit-signals are read from the RAM device one line at a time and are segregated into respective sub-pluralities. Each sub-plurality is tested to determine if there is logical value equality among all of the respective bit-signals. Test signals corresponding to each of the sub-plurality determinations are provided. The test signals are collectively evaluated and an overall equality or non-equality signal is derived.

  • Patent number: 6930953
    Abstract: A circuit takes a reference strobe signal as a first input, and a strobe ready signal generated from a memory that is strobed by the reference strobe signal as a second input. The circuit generates a self-timed strobe signal along with other control signals that are used to perform a subsequent memory access in a single clock cycle, thereby doubling memory access bandwidth.
