摘要：
Abstract: The thermometer digital-to-analog converter (DAC) is a distinctive architecture that plays a vital role in converting digital data into corresponding analog signals, the thermometer DAC employs a resistor network where each bit of the digital input corresponds to a unique resistor. It has notable drawbacks that need careful consideration. As the resolution of the DAC increases, the number of required current sources grows exponentially, leading to complex and demanding circuitry. This can escalate power consumption and occupy significant chip area, which is a critical concern in integrated circuit design. Furthermore, the current mismatch between the multiple current sources. Therefore, integrating memristors into DACs paves the way for more compact and efficient designs, reducing system complexity and enhancing reliability. The Voltage ThrEshold Adaptive Memristor (VTEAM) model of memristor is validated by using Virtuoso. In addition, a digital-to-analog converter based on memristor technology is implemented, taking advantage of the memristor’s compact size, minimal power usage, and a voltage threshold that is relatively low. The DAC design being proposed is based on a core DAC cell that consists of two memristors connected in opposing orientations. © Pleiades Publishing, Ltd. 2024.
