  • Parametric measurement of high-speed I/O systems
    Patent number: 7571363
    Abstract: A phase comparator is used to test a device under test comprising an input/output (I/O) circuit by applying a signal to the device under test; extracting a phase signal from the phase comparator; and determining parametric information pertaining to the I/O circuit of the device under test from the phase signal.

  • Adaptive decoder for skin effect limited signals
    Patent number: 6760551
    Abstract: The present invention is a decoder for decoding a signal. The decoder includes a discriminator and a threshold generator. The discriminator receives the signal and generates an output voltage equal to a first voltage if the signal is less than a threshold level that is input to the discriminator and equal to a second voltage if the signal is greater than the threshold level. The threshold level depends on the output from the discriminator in a preceding time interval that depends on the impulse response of a transmission link through which the input signal has passed. The threshold generator implements a low-pass analog filter that receives the output voltage during each of the clock periods and generates therefrom a filtered output signal.
