The complexity of the semiconductor manufacturing process is increasing day by day, involving hundreds of process steps, with the entire processing cycle from wafer to packaged chip lasting six to eight weeks. As process technology evolves from 90 nm to 3 nm, the requirements for feature size accuracy under SEMI standards have shown exponential improvement, … Read more
From portable players to various types of headphones, HIFIMAN has explored all products related to headphones and the audio field. However, the refresh rate for standalone amplifiers like this has been relatively slow. Recently, HIFIMAN launched its self-developed DAC plan – HYMALAYA. Many people noticed that on the day of the press conference, a desktop … Read more
Schiit has released a new decoder, which has been quite popular in the market recently, positioned at the flagship level with the model number DAC-R26. Priced at 8999 yuan, it seems that in recent years, there are fewer brands of decoders in the domestic market at the ten-thousand-yuan price point that have garnered attention. Schiit, … Read more
1. Introduction Recently, I built an R2R ladder resistor DAC circuit using resistors with a precision of one thousandth. Through testing, the circuit achieved a linear accuracy of 12 bits. Now, I ponder a question: if I reduce the order of R2R, for example to 12 bits, what would its linear accuracy be? Below, I … Read more
01 DAC Trapezoidal Resistor 1. Introduction Yesterday, I tested the development toolchain for the STM32G431. Today, I plan to try some interesting experiments. I saw a friend share their R2R trapezoidal resistor DAC solution on Bilibili, and I became quite interested. Therefore, I decided to test the performance of the trapezoidal resistor DAC solution using … Read more
