As … Read more
Recently, I came across a project that captures carbon dioxide directly from the atmosphere, which was quite shocking. China’s annual carbon emissions reach 14 billion tons, and the concentration of carbon dioxide in the atmosphere is 0.04% (400 ppm). Who thought of this brilliant idea to capture carbon from the air instead of focusing on … Read more
silly pid:113107781 by:paccha!! DAC (Digital to Analog Converter, 数模转换器) DAC 基础部分 The function of a DAC is to convert digital signals into analog signals. The working principle of a DAC is the opposite of that of an ADC. A DAC can convert digital signals into analog signals for output and control. DACs have a wide … Read more

Used to evaluate level compatibility, current driving capability, etc. when connected to MCU or FPGA: Parameter Description Condition Min Typical Max Unit Interpretation VIH High-level input threshold – 0.8×OVDD – – V Digital input … Read more
Click the blue text Follow us This Issue Focus Point B7-H4 is a member of the B7 immune checkpoint ligand family, which has been shown to bind to an unknown receptor on T cells, inhibiting T cell proliferation and cytokine production, thereby negatively regulating T cell function. The expression level of B7-H4 is elevated in … Read more
Click the blue text to follow meOn the battlefield against cancer, a new type of “weapon” is rising – the ADC (Antibody-Drug Conjugate) anti-cancer drug independently developed in China. The emergence of this drug has not only attracted the attention of the global pharmaceutical industry but has also given countless patients new hope. Why are … Read more
Author Information: Tang Kai1、Zhang Hu11Department of Medical Imaging, Wuhu Second People’s HospitalThis case is derived from the daily work findings of “Tang Kai”, and I must express my headache… My insight: The ADC map is one of the most common semi-quantitative data calculated by MR practitioners, and it is often the first encountered data… We … Read more
1. Problem Description: In ADC sampling circuits, especially in low-power product battery voltage sampling circuits, larger voltage divider resistors are typically chosen. This helps to reduce the additional power consumption caused by the voltage divider circuit. However, this can lead to inaccurate voltage sampling. 2. Problem Analysis When the ADC samples a single-ended voltage, if … Read more
This is essentially the mathematical version of the previous article; I prefer a more serious approach.Review of ADC Encoding Principles: The digital output of an ADC (ignoring quantization error) is: Where: Vin: Input signal voltage; Vref: Reference voltage; N: Number of bits of the ADC; Introducing Reference Voltage Noise Assume: Ideal reference voltage: Actual reference … Read more
