Abstract
A method of converting an N-bit digital code into analog output currents includes switchably connecting a first number of PN junctions to a positive output terminal and a second number of PN junctions to a negative output terminal based on the N-bit digital code; and switchably connecting a plurality of additional PN junctions to the positive output terminal and the negative output terminal based on the N-bit digital code, including connecting a first number of additional PN junctions to the positive output terminal based on the N-bit digital code and connecting a second number of additional PN junctions to the negative output terminal based on the N-bit digital code such that a first sum of the first number of PN junctions and the first number of additional PN junctions is equal to a second sum of the second number of PN junctions and the second number of additional PN junctions.
