Abstract
A Bias Unit Element (UE) comprises NAND gates with complementary outputs, the complementary outputs coupled through a charge transfer capacitor to a differential charge transfer bus comprising positive charge transfer lines and negative charge transfer lines. Each line of the differential charge transfer bus has a particular binary weighted line weight, such as 1, 2, 4, 2, 4, 8, and 4, 8, 16. Digital bias inputs are provided to the Bias UE NAND gate inputs, with a clear bit to initialize charge, and a sign input for enabling one of a positive Bias UE or negative Bias UE. A low-to-high transition causes a transfer of charge to the binary weighted charge transfer bus, thereby adding or subtracting a bias value from the charge transfer bus.
