Abstract
A digital to analog converter (DAC) includes a quantity of N cells including a Least Significant Bit (LSB) cell, a Most Significant Bit (MSB) cell and, N−2 cells ordered therebetween. Each of the N cells is configured to carry a current of I, 2*I, 4*I, 8*I, . . . , 2^(N−1)*I, respectively. At least the LSB cell includes a first cell element and a second cell element driven by a first current input and a second current input, respectively. A difference between a magnitude of the first current input and a magnitude of the second input current is approximately equal to I.
