Evolution of CMOS based NDR and its various applications

In this paper, we investigate different devices that can perform negative differential resistance property and the applications of an NDR device. An evolution from a conventional SET (single electron transistor) based NDR passing through various intermediate technologies such as RTDs, Lambda Diodes, HBTs (Hetero-junction Bipolar Transistor) towards CMOS based NDR has been discussed. Combining the advantages of CMOS i. e. cost, low power dissipation, area efficiency, noise, propagation delay, the most suitable technology has been selected for using the NDR (Negative Difference) operation and further application of the NDR device is proposed.
