C-element desirable effect. For example, using the ternary majority function defined as does not lead to the ternary C-element specified by the truth table, if the sum formula_6 is not split into pairs. However, even without such a splitting two ternary majority functions are suitable for building a ternary inclusive OR gate. Note that both the Maevsky and Tsirlin circuits are based actually on so-called David cell. Its fast transistor-level implementation is used in the semistatic C-element proposed. Yet another semistatic circuit using pass transistors (actually MUX 2:1) has been proposed. Other technologies suitable for realizing asynchronous primitives including C-element, are:
C-element and the latch outputs its previous state. There are also versions of semistatic C-element built on devices with negative differential resistance (NDR). It should be noted however, that NDR is usually defined for small signal. So, it is difficult to expect that such a C-element will operate in full range of voltages or currents. Since the majority gate is a particular case of threshold gate, any of known realizations of threshold gate can in principle be used for building a C-element. In the multiple-valued case, however, connecting the output of majority gate to one or several inputs may have no
