On Design of Memristive Amplifier Circuits

摘要

Amplifiers are essential building blocks of a majority of the mixed signal circuits that are used in the development of cognitive computing architectures. Their implementation and use is challenged by the second order effects that dominate the MOSFET operations with reduction in the technology size and scale. The ability to program the amplifiers once fabricated becomes an even more challenging problem as it warrants the use of multiple circuit components that lowers circuit performance and in turn outweighs the advantages of generalisation abilities. In this paper, a reconfigurable set of amplifier circuits are proposed based on quantised conductance devices in combination with MOSFET devices. The presented circuits form the basic configurations for the memristor based amplifiers, and show promising performance results in terms of power dissipation, on-chip area and THD values.
