Patent ID: 7098829

Claim:
A unit cell for a digital to analog conversion circuit comprising; a single current source (CS); a first data switch (S 1 ) coupled to the current source (CS); a second data switch (S 2 ) coupled to the current source (CS); a first phase switch (Phi 1 ) coupled between the current source (CS) and the first data switch (S 1 ) to provide a current to the first data switch; a second phase switch (Phi 2 ) coupled between the current source (CS) and the second data switch (S 2 ) to provide a current to the second data switch; a controller arranged to switch between the first (Phi 1 ) and second (Phi 2 ) phase switches in a Break Before Make alternating sequence, and to switch the first (S 1 ) and second (S 2 ) data switches in a Make Before Break sequence.
