Semiconductor Hub: August 2008
http://semiconductorhub.blogspot.com/2008_08_01_archive.html
Your semiconductor knowledge hub. Thursday, August 28, 2008. Paper transistor is one of the most important inventions in modern times. It revolutionized electronics and unlocked new and much, much smaller circuits. Portuguese researchers have produced the first discrete device. The cellulose not only used as substrate but also act as electric insulator by fabricating the device on both sides of the paper. Add to that the paper transistor outperforms the amorphous silicon thin-film transistor used in ...

Relay Components Hub: October 2008
http://relayhub.blogspot.com/2008_10_01_archive.html
Tuesday, October 7, 2008. Architecture of Low Dropout Linear Voltage Regulators. Have been valuable system components since the early days. One reason is the relatively low noise characteristic vis-à-vis the switching type of regulator. Others are a low parts count and overall simplicity compared to discrete solutions. But, because of their power losses, these linear regulators have also been known for being relatively inefficient. Or more popularly, the LDO. PD = VIN - VOUT IL VIN,Iground. The second te...

Your one point stop for all Electronic Communication related information. Monday, September 22, 2008. Smart Cards and Communicaiton. A Smart Card or Integrated Circuit. Card (ICC) is very small as any pocket-sized card with embedded integrated circuits which can process data. It can receive input which is processed by way of the Integrated Circuit Card applications and delivered as an output. This Integrated Circuit may consist only of EEPROM. Smart cards typically hold 2,000 to 8,000 electronic. Some di...

Semiconductor Hub: Types of Switched Capacitor Voltage Converters
http://semiconductorhub.blogspot.com/2008/09/types-of-switched-capacitor-voltage.html
Your semiconductor knowledge hub. Monday, September 22, 2008. Types of Switched Capacitor Voltage Converters. In the above circuit capacitor C1 is charged to the input voltage during first half of switching cycle. In the second half of switching cycle its voltage. During the time period of transient conditions start-up and steady state condition the capacitor C1 has to supply only a small amount of charge to the output capacitor on each switching cycle. The amount of. Voltage Doubler works similarly to t...
