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
Click to follow Xiaobai Learning Medicine BispecificADC is an active frontier, and today we will discuss whether bispecificADC is more effective than traditional monoclonal ADC in tumor toxin enrichment. Bispecific antibodies can be divided into two main categories: one type binds to two different antigens on different cells, acting as a connector, such as several … Read more
Various communication protocols are used in automotive ECUs. Previous articles introduced several serial communication methods, such as: Understanding the SPI Protocol: Principles, Architecture, and Applications Understanding the I2C Communication Protocol Understanding the Differences Between I2C and SPI Buses Chassis Domain Control: Have You Heard of AK and PSI5? In this article, we will introduce another … Read more
The UART (Universal Asynchronous Receiver/Transmitter) is a serial communication device that serves as a bidirectional, serial, asynchronous communication bus. It can achieve full-duplex communication using one data receiving line (RX), one data transmitting line (TX), and a ground line (GND). As shown in the figure below: When communicating using UART, the unit of transmission is … Read more
Ensuring system scalability is one of the core goals of our architectural design work. There are many ways to achieve scalability, and the JDK itself has a built-in SPI (Service Provider Interface) mechanism to help developers dynamically load various implementation classes, as long as these implementation classes follow certain development specifications. On the other hand, … Read more
1. Comparison of Communication Speeds: SPI, I2C, UART SPI > I2C > UART 1. Synchronous communication > Asynchronous communication; 2. In synchronous communication, a clock line must connect both ends of the transmission; 3. All are serial communication methods, while parallel communication is used for internal storage communication, such as flash; 4. The suitable transmission … Read more
The Electronic Enthusiast Network reports (by Wu Zipeng) that position sensors play a critical role in the industrial sector, capable of detecting parameters such as the position, displacement, distance, and angle of objects, thereby enabling automation control, precise positioning, and status monitoring. With continuous technological advancements, the application scenarios for position sensors are becoming increasingly … Read more
01 Dry Chemical Analysis Technology Dry chemical technology is compared to traditional wet chemical technology, where the liquid present in the sample serves as the reaction medium. The components to be measured react directly with dry reagents fixed on a carrier, allowing for qualitative observation or instrument detection (semi-quantitative) for chemical analysis. Single-layer Test Paper … Read more
