The analog-digital converter comprises a reference voltage production circuit, a comparator, a counter which can produce output codons and a reset circuit, wherein the reference voltage production circuit is connected with the antiphase end of the comparator; voltage is input to the in-phase end of the comparator; the output end of the comparator is connected with the counter which can produce the output codans through an OR gate; and the reset circuit is connected with the reference voltage production circuit. The analog-digital converter based on the memristor has the advantages that the precision is high, the power consumption is low, the occupied chip area is small, the structure is simple, the control is easy, and the analog-digital converter is suitable for low power consumption analog-digital conversion.

Description

technical field [0001] The invention relates to the field of semiconductor integrated circuits, in particular to an analog-to-digital converter based on a memristor, which is used for converting analog signals to digital signals. Background technique [0002] With the rapid development of electronic technology and the wide application of computers in automatic detection and automatic control systems, what are processed and transmitted by digital electronic computers are discontinuous digital signals, and most of them encountered in practice are continuously changing analog signals. After the analog quantity is collected and converted into an analog quantity of an electrical signal by a sensor, it needs to be converted into a digital signal by analog-to-digital conversion before it can be input into the digital system for processing and control. Therefore, it is used as an interface circuit for converting analog power into digital output. ——The analog / digital converter is the...

Problems solved by technology

At the same time, the higher the resolution of the ADC, the longer the conversion time required and the lower the conversion rate, so the resolution and conversion rate of the ADC are always mutually restricted.

Therefore, while developing a high-resolution ADC, it is necessary to take into account the high speed, and to develop a high-speed ADC while taking into account the high resolution. On this basis, power consumption, volume, portability, multi-function, and compatibility with computers and communication networks must also be considered. issues such as characteristics and special requirements in the application field, which also makes the structure and classification of ADC intricate
