Abstract
A method and apparatus for using multi-level signals in a gain cell is shown. The method involves of first, storing a value of a multi-level signal in the gain cell. A stepping waveform is then applied to the gain cell and the gain cell outputs a conduction signal when the level of the stepping waveform corresponds to the value of the multilevel signal that is stored within the gain cell. Finally, the value of the multi-level signal is determined through the conduction signal and the corresponding level of the stepping waveform. The gain cell includes an input device, a storage device and a level comparator, which responds to the stepping waveform generated from a stepping signal generator and outputs the conduction signal for determining the value of the multi-level signal stored in the storage device.
