This paper presents a strategy for implementing the discrete time version of the Nonlinear Energy Operator (NEO). The proposed implementation approach is based on the utilization of a circuit that produces an output current proportional to the square of its input voltage, which we call transconductor-squarer circuit. In order to avoid adverse effects of(More)
The present paper reports the design of a CMOS circuit capable of codifying the natural logarithm of an analog voltage in the relative phase of a train of pulses. The circuit is aimed to the implementation of a scale-independent pattern recognition system, based on the explanation provided by J. Hopfield for the human brain pattern-recognition computation(More)
