Abstract: An amplitude limiter circuit includes an inductor and a shunt circuit. The inductor has a first terminal connected to an input node. The shunt circuit is connected to a second terminal of the inductor and also is connected to a low impedance node. If an overvoltage condition forms on the input node, the shunt circuit forms an overvoltage current path from the input node, through the inductor, through the shunt circuit and to low impedance node.

Abstract: A circuit including an amplifier array including an amplifier stage with M amplifiers (M?2), connected to a resistor interpolator (interpolation order N?2) including an input row and at least a second row, each row comprising interpolation resistors connected in series at nodes. The input row including M driven nodes connected to a respective amplifier, and connected in parallel to the second row, with at least some first-row interpolation nodes connected to corresponding second-row interpolation nodes. The resistor interpolator comprising at least one multi-row interpolation cell, with: in the input row, a driven node coupled through first and second interpolation resistors to respective adjacent first and second interpolation nodes; and in the second row, third and fourth interpolation nodes coupled through third and fourth interpolation resistors to an intermediate fifth interpolation node; and with the first and second interpolation nodes connected respectively to the third and fourth interpolation nodes.

Abstract: Some aspects of the disclosure are directed to a transmission circuit that includes a main driver. The transmission circuit also includes a plurality of capacitive modules connected in parallel to the main driver. A controller also is included that is coupled to the plurality of capacitive modules. The controller selectively enables and disables each capacitive module to implement a target amount of pre-emphasis.
