A fully-differential switched-current (SI) circuit provided with clock-feedthrough (CFT) and common mode rejection and offset compensation schemes is described. Different from a conventional SI memory cell, it takes the difference between two differential inputs to deliver the balanced differential currents. Transistor level simulations and error analyses are given to demonstrate its performance.
