Holding preserving in RTD-based multiple-valued quantizers

Multiple-valued logic (MVL) circuits are one of the most attractive applications of the monostable-to-multistable transition logic (MML), and they are of the basis of advanced circuits for communications. The operation of a quantizer has two steps: sampling and holding. Once the quantizer samples the signal, it must maintain the sampled value even if the input changes. However, holding property is not inherent to RTD-based MML circuit topologies. A procedure to obtain the relation between circuit parameters in order to achieve a correct operation is described.
