Design of a CMOS memristor emulator-based, self-adaptive spiking analog-to-digital data conversion as the lowest level of a self-x hierarchy

Abstract: Abstract. The number of sensors used in modern devices is rapidly increasing, and the interaction with sensors demands analog-to-digital data conversion (ADC). A conventional ADC in leading-edge technologies faces many issues due to signal swings, manufacturing deviations, noise, etc. Designers of ADCs are moving to the time domain and digital designs techniques to deal with these issues. This work pursues a novel self-adaptive spiking neural ADC (SN-ADC) design with promising features, e.g., technology scalin… Show more

“…The second stage, the self-adaptive spike-to-digital converter (SA-SDC), generates a digital code corresponding to the TD value. The three core principles of Jeffress's theory are integrated into the SA-SDC through synapse weights, an array of adaptable coincidence detection, and a winner-takes-all (WTA) mechanism with memory [18]. In our chip, we addressed the aforementioned issues by making two contributions to the universal-sensor-interface with self-X properties (USIX), as described in our earlier publication [16].…”

“…By adding more ACDs in a cascade, the ability to measure time intervals between in1 and in2 can be enhanced, resulting in an increased resolution of the SA-SDC. The number of ACDs needed to achieve a specific number of bits (NOB) can be determined using Equation (1), which was developed in [18].…”
