With the rise of portable mobile devices and various wearable technologies, we must pay attention to the power consumption issues of these devices, as they all share a common characteristic: they are powered by battery systems. A single circuit board may contain many unit circuits related to power consumption. Today, we will discuss the low … Read more
Today, I plan to start a new series on low power design. Although my experience in low power design is not extensive, I have worked on projects with high demands for low power consumption, so I have a general understanding of the common practices and main techniques in low power design. Additionally, due to various … Read more
1 Introduction The previous article reviewed the hierarchical methods of low power design【Technical Review】, and this article further discusses some of the key points. This is particularly beneficial for those who are new to low power design, as it may provoke more thoughts. 2 Why Low Power Design is Necessary The previous article mentioned several … Read more
Before learning about low power consumption in PIC microcontrollers, let’s briefly go over some basic knowledge and concepts related to low power consumption. Power (Watts) = U (Volts) * I (Amperes) Energy (Joules) = U (Volts) * I (Amperes) * t (Seconds) Charge (Coulombs) = I (Amperes) * t (Seconds) Power consumption can be divided … Read more
Embedded Development in C: Low Power Design In embedded systems, low power design is a crucial topic. With the proliferation of Internet of Things (IoT) devices, how to reduce energy consumption while ensuring performance has become a challenge that developers must face. This article will introduce some basic principles of low power design and demonstrate … Read more
This article was originally published in the Zhihu column [The Path of Digital IC Backend Engineers]. In the field of low power design, the most effective way to reduce power consumption is through power shutdown. This is because no matter how low the voltage, how small the current, how slow the speed, or how minimal … Read more
Classification and application of power switches: Low Power Design – Power Switch In a recent project, with tight deadlines, we ran two versions, differing in whether to use UPF. The block is implemented normally, and the switch is added at the top level. 1. UPF First, let’s analyze the UPF content related to the power … Read more
Author:RimeLink Source: http://blog.csdn.net/jiangjunjie_2005/article/details/47700597 Introduction: Power consumption is a significant issue for battery-powered products; once the energy is depleted, the device will “stop working.” In “Low Power Design of MCUs (Part 1) Theory,” we introduced the principles of energy saving; in “Low Power Design of MCUs (Part 2) Practice,” we measured the low power consumption values … Read more
1. Concept Composition of Power Consumption: Three main sources of power consumption: surge, static power, and dynamic power; Surge Current: Refers to the maximum instantaneous input current generated when the device is powered on, known as the inrush current; The surge current is device-dependent; Surge power is not our primary concern, so it is only … Read more
1.1 Overview Over the past two decades, the design of complex chips has undergone a series of transformations. In the 1980s, language-based circuit design and synthesis emerged. In the 1990s, design reuse and IP became mainstream design practices. In recent years, low power design has begun to change the way designers handle complex SoC designs … Read more
