Abstract :
A distortion analysis based on the large signal behavior of the basic switched-current memory cell is presented. In the first part, based on a closed form solution of the step response, distortion due to the settling error is addressed. In the second part, distortion caused by clock-feedthrough is analysed. The solutions are compared with simulated and/or measured results. Furthermore, harmonic terms above the fifth are shown to be negligible
