2024年5月26日 · Analogue to Digital Converter, or ADC, is a data converter which allows digital circuits to interface with the real world by encoding an analogue signal into a binary code.

» An analog-to-digital converter (A/D or ADC) produces a digital number corresponding to an analog input voltage sample. » Flash ADC Consists of a series of comparators, each one comparing the input signal to a unique reference voltage.

The present manuscript focusses on the design of an ultra-low power 2- bit flash analog to digital converter. The flash analog to digital converter is implemented using a modified double-tail latch type comparator that consumes a minimal power of 0.65 µW and a delay of 133ps for an operational voltage of 0.6V at 16m technological node.

2018年6月8日 · 我们知道ADC的转换结果是一个unsigned类型，根据数据的四舍五入取舍即可计算得到答案。 比如上图10-bit的ADC，为什么0.012V转换结果是2,而0.014V转换结果是3？

This paper presents an energy and area-efficient successive approximation register (SAR)-assisted cyclic analogto-digital converter (ADC) architecture. The proposed hybrid ADC combines a 2-bit/cycle cyclic ADC with a slack-borrowing coarse SAR ADC.

Flash Type ADC is based on the principle of comparing analog input voltage with a set of reference voltages. To convert the analog input voltage into a digital signal of n-bit output, (2 n – 1) comparators are required. The following figure shows 2- bit flash type ADC. The three op-amps are used as comparators.

2022年7月12日 · We only need two bits of information to distinguish between the four voltage levels. Even the cheapest ADCs give a whole eight bits -- the cheapest ADC on Digikey right now gives you eight bits and communicates over SPI, and would cost just under a dollar a piece.

摘要: 基于180nm CMOS工艺，设计了一种2 bit/cycle结构的8 bit、100 MS/s逐次逼近模数转换器（SAR ADC）. 采用两个DAC电容阵列SIG_DAC、REF_DAC实现了2 bit/cycle量化，其中SIG_DAC采用上极板采样大大减少了电容数目，分裂电容式结构和优化的异步SAR逻辑提高了ADC的转换速度.

2022年1月25日 · 一个N位flash ADC包括2^N个电阻和2^N–1个比较器，每个比较器均从电阻串获得基准电压，且每个基准电压要比链中的下一个基准电压大1LSB。 对于给定输入电压，低于某个点的所有比较器都将出现输入电压高于基准电压且逻辑输出为“1”，而高于该点的所有比较器 ...
