Among many uses, diodes are found in rectifiers to convert alternating current (AC) power to direct current (DC), demodulation in radio receivers, and can even be used for logic or as temperature sensors. A common variant of a diode is a light-emitting diode, which is used as electric lighting and status indicators on electronic devices.

2014年3月10日 · Diode Definition: A diode is defined as a component that restricts the direction of flow of electric current, mainly allowing current to pass in one direction. Symbol and Orientation: The diode symbol represents the direction of conventional …

It conducts electric current in only one direction and restricts current from the opposite direction. A diode is reverse biased when it acts as an insulator and is forward biased when it allows current to flow. A diode has two terminals, the anode and the cathode.

In this article, let us understand in detail about what is diode and diode symbol. What Is a Diode? Diodes are used to protect circuits by limiting the voltage and to also transform AC into DC. Semiconductors like silicon and germanium are used to make the most of the diodes.

2016年4月12日 · 当你从cadence的 ADE 界面，result下面的print功能里，有个叫DC operation points，你就能从中找到gds。 Ro就是gds的倒数。 然后，你就能很容易的发现，gds是个远小于gm的数字。 比如一般gm可能有10u，那么gds可能只有80n。 作者君是个又懒又笨的家伙，什么电阻并联等于电阻的倒数之和再倒数……晕晕……算不来！ 那好吧，怎么才能更加直接的看出来呢？ 电流是可以直接相加的！ 因为gm乘以电压就是电流嘛，几条电流支路的总和就等于所有电流 …

By optimizing the extraction diode geometry and reducing the beam current, the spherical aberration was later improved and therefore the beam profile became more uniform. 示例中的 …

蓝色的线就是diode的等效电阻，红色的是diode的电压。 为了做个比较，作者君量了一下这个800nm/10um的pmos在1uA时候的电压，比较接近1V，所以作者君加上了一个理想的1M欧姆电阻的电压线，就是上面图里浅紫色虚线；然后还有理想的电阻值，就是那根横着的黄线。 所以，大家可以清楚的看到diode等效电阻的变化：电流1pA的时候，等效电阻达到了70多GOhm；然后在1mA的时候，电阻只有232kOhm；中间有个极小值，应该是因为随着电流越来越大，各种次 …
