Abstract :
A comparison between two novel device architectures for Few Electron Negative Differential Resistance (NDR) devices is presented. The first architecture, based on two cross-connected SETs, offers ultra low power dissipation with low current drive (∼nA). The second architecture, founded on CMOS-SET hybrid technology, exhibits high current drive (∼pA) and easy interface with CMOS devices at sub-ambient temperature regime (-1000°C to -1500°C). The proposed device architectures, simulated by Monte Carlo simulation and analytical models, reveal Negative Differential Resistance (NDR) behaviour, which can be tuned by external current bias. The application of proposed NDR architectures as an analog amplifier is also demonstrated.
