Abstract

Neuromorphic systems typically use VLSI circuits and devices that implement models of biological systems for processing sensory signals. The analog circuits used in neuromorphic systems operate on signals that change slowly in time, with biological time-constants of the orders of milliseconds, and are characterized by very low-power consumption. Here we present a low– power circuit, with small slew-rate, that can be used as a building block in neuromorphic systems for dual threshold comparison. The circuit is compact, operates in weak-inversion, and dissipates power only when the input signal is within a required range.
