A CMOS Frequency Comparator based on Jamming Avoidance Response of Eigenmannia
نویسندگان
چکیده
In this paper, we implement a model of an electric fish, Eigenmannia, that detects frequency differences between the individuals, on analog CMOS circuits. The circuit’s fundamental function is equivalent to a conventional CMOS frequency comparator, although less post-processing is still required. The circuit consists of Pand T-units each of which encodes amplitudes and phases of the monitored electronic signals, respectively. Using a simulation program of integrated circuit emphasis (SPICE), we demonstrate that the proposed circuit can detect the phase difference effectively.

Resolving competing theories for control of the jamming avoidance response: the role of amplitude modulations in electric organ discharge decelerations.
The algorithm for the control of the jamming avoidance response (JAR) of Eigenmannia has been the subject of debate for over two decades. Two competing theories have been proposed to explain how fish determine the correct direction to shift their pacemaker frequency during jamming. One theory emphasizes the role of time-asymmetric beat envelopes, while the other emphasizes the role of amplitude...
متن کاملThe jamming avoidance response in Eigenmannia is controlled by two separate motor pathways.
The gymnotiform fish Eigenmannia generates weakly electric signals for electrolocation and communication. The signals are produced by electric organ discharges (EODs) that are driven by a medullary pacemaker nucleus. To avoid jamming by neighboring conspecifics with similar frequencies, a fish raises its own EOD frequency if the neighbor's frequency is lower, and it lowers its EOD frequency if ...
متن کاملClosed-loop stabilization of the Jamming Avoidance Response reveals its locally unstable and globally nonlinear dynamics.
The Jamming Avoidance Response, or JAR, in the weakly electric fish has been analyzed at all levels of organization, from whole-organism behavior down to specific ion channels. Nevertheless, a parsimonious description of the JAR behavior in terms of a dynamical system model has not been achieved at least in part due to the fact that 'avoidance' behaviors are both intrinsically unstable and nonl...
متن کاملWaveform discrimination, phase sensitivity and jamming avoidance in a wave-type electric fish
The electric organ discharge (EOD) of most species of the freshwater knifefishes (Gymnotiformes) of South America is of the wave, not the pulse, type. Wave EODs are usually of constant frequency and amplitude, and show a bewildering multitude of species-characteristic waveforms. The EOD of Eigenmannia is sexually dimorphic in waveform and in the intensity of its higher harmonics. In a go/no go ...
متن کاملThe Sexually Dimorphic Jamming Avoidance Response in the Electric Fish Eigenmannia
Eigenmannia's jamming avoidance response (JAR) is a frequency change of its electric organ discharge (EOD) in response to an electric stimulus of similar frequency (small AF; AF = FFlgh — FStlm). It is assumed that the response to an undamped stimulus, AR = FRMponM. — F R M I , is stereotyped and non-habituating, and improves the fish's electrolocation performance in the presence of a jamming s...
