Testing and Debugging PMICs with Ease Friday, September 22, 2023
Adaptive Power Optimization is Revolutionizing PMICs “There is no better way to save energy and cut bills than by turning all electronic devices off.” This basic piece of advice is the underlying principle and philosophy behind any form of energy management applied to energy consumption optimization, and in general in so-called adaptive power optimization. In the case of battery powered …
Energy Storage Devices: a Battery Testing overview Wednesday, July 28, 2021
Energy storage device testing is not the same as battery testing. There are, in fact, several devices that are able to convert chemical energy into electrical energy and store that energy, making it available when required. Capacitors are energy storage devices; they store electrical energy and deliver high specific power, being charged, and discharged in shorter time than batteries, yet with …
How to Measure a MOSFET I-V Curve
如何测量 MOSFET I-V 曲线 Thursday, May 27, 2021
为了确保 MOSFET 的正常运行并符合规格要求，一个有效的方法是通过追踪其 I-V 曲线来确定其特性。有许多输出特性需要进行 I-V 测试；您只需跟踪 I-V 特性并验证设备是否正常工作，就能得出栅极漏电、击穿电压、阈值电压、传输特性和漏极电流。 吉时利的源测量单元 (SMU) 是 MOSFET I-V 特性测试的核心仪器。它们能够在测量电流的同时提供电压源，或者在测量电压的同时提供电流源，而且可以与直流和扫描操作相结合，用于执行正向电压 (VF)、反向漏电和反向击穿电压 (VB) 等测量任务，而无需更改与被测设备 (DUT) 的连接方式（图 1）。 通过使用内置功能，多个 SMU 可以同步执行各种参数测量，包括阈值电压、贝塔值和跨导。 使用吉时利源测量单元测量 MOSFET 的 I-V 曲线 只需两台 SMU 仪器就能获得一系列 MOSFET 曲线（图 2）。对于来自 …

2 Series MSO24 Mixed Signal Oscilloscope
How to Choose the Best Oscilloscope to Buy Tuesday, May 11, 2021
Basic Parameters for Choosing an Oscilloscope Oscilloscope Bandwidth Bandwidth is a key spec that determines the highest frequency your oscilloscope can measure accurately. It's a vital consideration affecting both the functionality and cost of the oscilloscope. The higher the bandwidth, the more accurate the reproduction of your signal, as illustrated with a signal captured at 250 MHz, 1 GHz …

什么是示波器探头？ Monday, May 3, 2021
示波器探头是一种在测试点或信号源 与示波器之间建立物理和电气连接的设备。 根据您的测量需求，这种连接既可以通过一根简单的导线实现， 也可以使用有源差分探头等高精度仪器来完成。从本质上说，探头是一种设备或网络， 用于将信号源与示波器的输入端连接起来。 示波器探头的工作原理 示波器探头在信号源或被测设备 (DUT) 与示波器之间提供高质量的连接。在选择和使用示波器探头时，有许多重要的考虑因素，包括 物理附件、对电路操作产生的影响以及信号传输。 示波器探头的解析 大多数探头至少有一至两米长的电缆。当探头需要在被测电路的 不同测试点之间移动时，探头电缆使得示波器可以稳定地放置在小车或工作台上， 无需随之移动。然而，在某些情况下，探头电缆可能会降低探头的带宽。因此，电缆越长 ，带宽降低也会越多。 大多数探头都有一个带探头端部的探头头部或手柄 …

Chamber for an EMC/EMI precompliance test
The Financial Case for an EMI/EMC Pre-Compliance Test Solution Tuesday, April 20, 2021
Failing EMI compliance testing can be a design engineer’s worst nightmare. Additional compliance testing costs, external lab testing, debug engineering time, and in some cases, board spins can add significant costs and time delays to your project. Unfortunately, for companies new to EMI/EMC, estimating compliance testing cost can be somewhat challenging. In this blog, we’ll provide information on …
