Abstract

Embodiments relate to peaking inductor array for a peaking control unit of a transceiver. An aspect includes the peaking inductor array comprising a plurality of cells connected in parallel, each cell comprising a respective active inductor. Another aspect includes each of the plurality of cells further comprising a decoupling capacitor.

First claim

What is claimed is:

1. A method for controlling peaking of a peaking control unit of a transceiver, the method comprising:
forming a peaking inductor array, the forming comprising:
connecting a plurality of cells in parallel, wherein each cell comprises a respective active inductor, a respective decoupling capacitor, and a respective selectable resistor, wherein each respective active inductor comprises a respective first field effect transistor (FET) and a respective second FET, and wherein each respective selectable resistor comprises a respective switch in series with a respective resistor;
connecting the respective first FET in series with the respective second FET for each respective active inductor;
connecting the respective decoupling capacitor and the respective selectable resistor for each cell in series; and
connecting each of the respective decoupling capacitor and the respective selectable resistor in parallel with the respective first FET for each cell, wherein a capacitance of the respective decoupling capacitor in each cell is larger than intrinsic and extrinsic capacitances of the respective active inductor;

providing the peaking inductor array in the peaking control unit, wherein the providing comprises connecting the peaking inductor array in parallel with a direct current (DC) diode array in the peaking control unit; and
controlling peaking of the peaking inductor array in two dimensions by opening or closing at least one respective switch.
