    Abstract: Systems and methods are provided for improving signal propagation. A repeater segments a transmission line into a first and a second line. The repeater includes an inverting amplifier and an equilibration circuit. The inverting amplifier has an input connected to the first line and an output connected to the second line. The amplifier receives and an input signal at a first logic potential and transmits an output signal at an inverted second logic potential during and an active portion of a cycle. The equilibration circuit electrically isolates the first line and the second line and shorts the first line to the second line during and an inactive portion of the cycle. Upon completion of the inactive portion of the cycle, the first line and the second line have substantially equal starting potentials between the first logic potential and the second logic potential. Setting the starting potential between the first and second logic potentials shortens the delay associated with a transition between logic potentials. Additionally, one embodiment of the equilibration circuit selectively disconnects the amplifier from the power rails.

    Abstract: A logic gate that includes a first differential amplifier and a feedback circuit. The first differential amplifier has a number of first (e.g., non-inverting) inputs and a second (e.g., inverting) input, receives and senses input signals applied to the non-inverting inputs, and provides a differential output that is a particular logic function (e.g., an ‘OR’) of the input signals. The non-inverting inputs may correspond to the gates of a number of transistors coupled in parallel to form an OR function. The feedback circuit detects the (e.g., non-inverting node of the) differential output and provides a control signal for the inverting input of the first differential amplifier. The logic gate typically further includes a second differential amplifier that senses and further drives the differential output.

    Abstract: A compensating buffer providing both course tuning on initialization and fine-tuning during operation is disclosed. The course tuning is provided by a plurality of binary-weighted driver legs which are selected during initialization. The fine-tuning which is selectable during both initialization and during operation is provided through linear-weighted biasing. The linear-weighted biasing is simplified through the use of a digital-to-analog converter.

    Abstract: An output driver circuit for a semiconductor device. In one embodiment, the output driver is coupled to an output terminal of the semiconductor device and consists of an N-channel pull-down transistor and a P-channel pull-up transistor formed in an N-well in a P-type substrate. A tie-down region formed in the N-well is selectively coupled to a supply potential by means of a decoupling transistor, and during normal operation of the driver maintains the supply voltage bias of the N-well. An overdrive detection circuit is coupled to the output terminal. Upon detection of an overdrive condition on the output terminal, such as a voltage exceeding a predetermined maximum, or excessive current injected into the output terminal (or both), the overdrive detection circuit deasserts a control signal applied to the gate of the decoupling transistor, thereby decoupling the N-well from the supply potential. In one embodiment, the decoupling transistor is not coupled to the output terminal.

    Abstract: A current mode driver includes a tail current device, a differential pair of input transistors, cascode output transistors, and pre-charge circuits to charge cascode nodes between the differential pair of input transistors and the cascode output transistors. The current mode driver is driven by CMOS drivers that alternately turn the input transistors on and off. A wide-swing bias circuit provides bias voltages for the current mode driver. This bias voltage for the tail current device is closely matched to provide current matching between the bias circuit and the current mode driver.
