This is a short paper. It is not recommended to do this in practice, but it is theoretically acceptable. The reason is that the dynamic range is not 1+1=2, but rather <2. Moreover, in 2025, the performance of devices has improved significantly; the simpler, the better. Complex signal chains do not provide much performance improvement … Read more
Today is Wednesday, and the week is halfway through. Happy Wednesday, everyone. In the previous article (【Detailed Explanation of the Camera Body】Revisiting Sensors: Native ISO and Extended ISO), we discussed the concepts of native ISO and extended ISO. It was mentioned that ISO affects dynamic range. Today, we will briefly explain this issue. 01 The … Read more
Follow our business 👇 Scan to subscribe 1. Signal-to-Noise Ratio (SNR): Why Are Some Photos Clean in Low Light While Others Are Full of ‘Snow’? You have definitely encountered this situation: when taking night scenes under streetlights, some smartphones can reproduce the warm light of the streetlight, with even the texture of the leaves clearly … Read more
The value of audio chips lies not only in their ability to “play sound” but also in whether they can make the sound feel “natural and comfortable.” A key component in this process is the DAC (Digital-to-Analog Converter). The music or speech we hear daily starts as digital signals of 0s and 1s within the … Read more
Recently, Sony Semiconductor Solutions Corporation (SSS) officially unveiled its groundbreaking three-layer stacked image sensor technology during its strategic presentation to investors. This revolutionary design is not merely a pixel enhancement but fundamentally rethinks the architecture of the sensor from the ground up, aiming to bring a qualitative leap in future imaging performance and solidify its … Read more
1. Digital Gain Adjustment Method 20 * ln x = 8dB, calculating the value of x gives the multiple of the digital gain to be increased. for(int i=0;i<samples;i++){ pcm[i] = pcm[i] * powf(10.0,要调节增益大小/20.0);} 2. Dynamic Range Formula Dynamic Range = 20 * log( Maximum Value / Minimum Value) Example: The integer range represented by a … Read more
01Research Overview With the rapid development of molecular diagnostic technologies, digital CRISPR technology has become an important tool for nucleic acid detection due to its single-molecule counting and absolute quantification capabilities. However, traditional digital CRISPR platforms face significant challenges in several aspects. Firstly, most existing platforms adopt equal-volume microcavity designs, which typically cover a dynamic … Read more
Recently, Sony launched the 50-megapixel CMOS image sensor LYT-828, which features a dynamic range exceeding 100dB. This breakthrough significantly enhances the imaging quality of smartphone photography, particularly in suppressing highlight overexposure, dark noise, and performance in low-light environments, achieving industry-leading levels.LYT-828 achieves a dynamic range of over 100dB through the integration of single-frame HDR (based … Read more
Written by | AUTO Chip Sphere Author | Lei Man The so-called pre-order data publicity from Chinese new energy vehicle companies has become a joke! Xiaomi YU7 announced 289,000 pre-orders in just one hour. I just want to ask, all those who only announce how many units they have pre-ordered, without providing actual evidence, what … Read more
“A 12-bit 104-MS/s SAR ADC in 28nm CMOS for Digitally-Assisted Wireless Transmitters”The calibration method introduced here utilizes low-level capacitors to calibrate high-level capacitors, as the absolute mismatch of high-level capacitors is greater, which in turn has a larger impact on DNL and INL. Calibrating high-level capacitors can effectively improve the dynamic range of the ADC.As … Read more
