Abstract
A Bias Unit Element (UE) has a digital input and sign input, and comprises a positive Bias UE and a negative Bias UE, each comprising groups of NAND gates generating an output and a complementary output, each of which are coupled to differential charge transfer lines through binary weighted charge transfer capacitors to a differential charge transfer bus comprising a positive charge transfer line and a negative charge transfer line. The sign input enables the positive Bias UE when the sign bit is positive and enables the negative Bias UE when the sign bit is negative.
