Current source array for high speed, high resolution current steering DACs

A current source array comprising, in a thermometer coded current steering digital to analog converter:

• M2 current sources arranged in an array having an even number of columns 1 through M and an equal number of rows 1 through M;
• the outputs of the current sources in even numbered rows of the first column each being connected to the output of a current source in each of the other columns located along a first diagonal through the array from the respective current source in the first column;
• and,
• the outputs of the current sources in odd numbered rows of the first column each being connected to the output of a current source in each of the other columns located along a second diagonal through the array from the respective current source in the first column, the second diagonals being in an opposite diagonal direction from the first diagonals.

A current source array comprising:

• a plurality of current sources arranged in an array of columns and rows;
• the outputs of the current sources in even rows of the first column each being connected to the output of a current source in each of the other columns located along a first diagonal through the array from the respective current source in the first column;
• and,
• the outputs of the current sources in odd rows of the first column each being connected to the output of a current source in each of the other columns located along a second diagonal through the array from the respective current source in the first column, the second diagonals being in an opposite diagonal direction from the first diagonals.
