Efficient Algorithm for Simulating On-Chip RLC Interconnects
This is a technique to simulate the on-chip transient output response of a distributed RLC interconnect. The method is based on direct pole extraction of an exact transmission line transfer function. Closed form expressions of the poles are developed for the zero driver resistance case. To utilize these expressions, an interconnect system with a...

Ballistic Deflection Transistor and Ballistic Deflection Transistor Based Logic Circuits
The nano-scale structures of the transistor are smaller than the mean-free path of the electrons, which travel in a ballistic, non-ohmic manner in the semiconductor. The device does not have a conventional junction, like convenitional transistors, and uses a non-linearity phenomenon which only exists in the ballistic regime. Applications: T...

Distributed Amplifiers with Built-In Filtering for UWB Impulse Radio
Brief Description: This technology provides a distributed amplifier (DA) with built-in, on-chip filters so that the frequency response of the distributed amplifier is controlled, on chip, not only within the pass band, but also in the transition and stop bands. The very precise filtering is particularly useful for UWB impulse radios, which n...
