“READING” When feeling anxious, instead of going in circles, it is better to turn the pages of a book. Every step of learning is taking root for the future. Every moment spent focused today is the confidence for tomorrow. Don’t be afraid of going slow; just start, and growth will quietly happen. Cultivate with peace … Read more
1. Explanation of Core Concepts DAC (Digital-to-Analog Converter): Its function is to convert digital codes (0s and 1s) into real analog voltage or current signals. It serves as a bridge between the digital world and the analog world. Sampling Rate: Refers to the number of times the DAC can perform this conversion operation per second. … Read more
Following antibody-drug conjugates (ADCs), a new drug form known as “Degrader-Antibody Conjugate” (DAC) is gaining attention in the field of oncology and other diseases due to its unique “targeted protein degradation” mechanism. 1 What is DAC?DAC, short for Degrader-Antibody Conjugate, is an innovative drug conjugation technology. It cleverly combines the targeting specificity of monoclonal antibodies … Read more
The SPI (Serial Peripheral Interface) communication protocol is a high-speed, full-duplex, synchronous, master-slave architecture serial communication protocol that uses only four signal lines. It is widely used for data transmission between MCUs/FPGA and peripherals (such as DACs, ADCs, Flash, and EEPROM).This article will explain the SPI communication protocol in three parts: the physical layer, protocol … Read more
