Abstract
A device includes source circuitry comprising a first portion of a current mirror and a first transistor. The device also includes load circuitry comprising a second portion of the current mirror and a second transistor, wherein the load circuitry is disposed at a distance from the source circuitry. The device further includes a path coupled to a first gate of the first transistor and to a second gate of the second transistor, wherein the path provides a predetermined voltage to both of the first gate of the first transistor and to the second gate of the second transistor.

A device, comprising:
- source circuitry comprising a first portion of a current mirror and a first transistor;
- load circuitry comprising a second portion of the current mirror and a second transistor, wherein the load circuitry is disposed at a distance from the source circuitry;
- and
- a path coupled to a first gate of the first transistor and to a second gate of the second transistor, wherein the path provides a predetermined voltage to both of the first gate of the first transistor and to the second gate of the second transistor.
A device, comprising:
- source circuitry comprising a first portion of a current mirror and a first transistor;
- load circuitry comprising a second portion of the current mirror and a second transistor, wherein the load circuitry is disposed at a distance from the source circuitry;
- and
- voltage generation circuitry coupled to each of the source circuitry and the load circuitry, wherein the voltage generation circuitry when in operation generates a reference voltage and transmits the reference voltage to both of a first gate of the first transistor and to a second gate of the second transistor.
A method, comprising:
- generating an source current in a first portion of a current mirror;
- generating an output current in a second portion of the current mirror;
- determining if a first value of the output current matches a second value of the source current;
- closing a first switch disposed in parallel with a first transistor coupled to the first portion of the current mirror when the first value of the output current is determined not to match the second value of the source current;
- and
- closing a second switch disposed in parallel with a second transistor coupled to the second portion of the current mirror when the second value of the output current is determined not to match the second value of the source current.
