Abstract: A carrier layout comprising a substrate comprising a ground plane layer and a coplanar waveguide interconnect disposed onto the substrate. The coplanar waveguide interconnect comprises a pair of coplanar conductors and a central conductor disposed between the pair of coplanar conductors. The coplanar conductors of the pair are electrically connected to each other by at least one conducting island that is isolated from the ground plane layer. The present invention also provides an interconnect structure for coupling an electronic unit to an optical device disposed on a substrate having a ground plane layer, the interconnect structure comprising a pair of coplanar conductors and a central conductor disposed between the pair of coplanar conductors. The conductors of the pair are electrically connected by at least one conducting island that is isolated from the ground plane layer.

Abstract: A balanced differential transimpedance amplifier with a single-ended input operational over a wide variation in the dynamic range of input signals. A threshold circuit is employed to either or a combination of (1) generate a varying decision threshold to ensure a proper slicing over a wide range of input current signal levels; and (2) generate a bias current and voltage applied to an input of a transimpedance stage to cancel out a dependence of the transimpedance stage voltage input on input current signal levels.

Abstract: A power efficient device for driving a load comprising a low current path and a high current path, wherein the high current path is driven by a first voltage source. In order to accommodate larger turn on voltages of possible load devices while maintaining low power operation, an additional voltage source exceeding the voltage source in the high current path is introduced in the low current path.
