Taper routing in high-speed interfaces for compensating impedance mismatches

A method comprising:

• forming a conductive region having a geometry that varies along a longitudinal direction to create a taper;
• configuring the taper to produce a spatially varying characteristic impedance along the conductive region;
• coupling a first electronic component to a first edge located at one end of the conductive region;
• coupling a second electronic component to a second edge located at an opposite end of the conductive region;
• and
• transitioning the characteristic impedance from a first impedance at the first edge to a second impedance at the second edge to reduce an impedance mismatch between the first electronic component and the second electronic component.

A high-speed electronic system comprising:

• a transmitter;
• a receiver;
• and
• a conductive region coupled between the transmitter and the receiver;
• wherein the conductive region has a geometry that varies along a longitudinal direction to form a taper, the taper being configured to produce a spatially varying characteristic impedance along the conductive region;
• wherein the characteristic impedance transitions from a first impedance at a first edge located at one end of the conductive region to a second impedance at a second edge located at an opposite end of the conductive region;
• and
• wherein the spatially varying characteristic impedance is configured to reduce an impedance mismatch between the transmitter coupled to the first edge and the receiver coupled to the second edge.
