  • Differential input buffer bias pulser
    Publication number: 20020118592
    Abstract: An integrated circuit clock buffer is described which includes a pulser circuit having a delayed feedback to provide a pulsed signal in response to a transition in the external clock signal. The pulser circuit includes a delay element having an output node coupled to the input node of an inverter. The delay element and inverter are coupled between a first and second transistor. The buffer circuit generates non-skewed internal clock signals.

  • Device and method for electrostatic discharge protection of a circuit device
    Patent number: 6181540
    Abstract: An circuit device includes a stack of electrostatic discharge protection devices shared between a plurality of contact pads on the device. In addition, each contact pad is coupled to its own individual protection device. Together, the individual protection devices and the stack establish a trip point for shunting a charge from the contact pads in the event that any of the pads reach a voltage potential greater than the trip point. In doing so, the stack protects internal operations circuits from damage. At the same time, the shared stack conserves die space.

  • Waveshaping circuit generating two rising slopes for a sense amplifier pulldown device
    Patent number: 5614856
    Abstract: A waveshaping circuit for a sense amplifier pulldown device receives a standard digital signal at its input and independently creates a signal with two distinct rising slopes at its output. This unique output signal activates the sense amplifier pulldown device slowly at first with the first rising slope then quickly saturates it with the second rising slope allowing the sense amplifier to accurately sense and amplify the voltage difference between two digit lines.
