It's a Buck; It's a Boost, No! It's a Switcher! News & Analysis 4/2/2003 Post a comment The LSD cell has no hallucinogenic properties, insists Sanjaya Maniktala in this new tutorial article series on switching power supply design. Rather, if you can visualize the inductor (L), the switch (S) and the diode (D) associated with the power FETs, you're in a better position to see how they behave in switchmode regulator designs. There are four LSD cell types: Some are easier to turn on; some are easier to turn off. Guess which support buck typologies, which support boost. Planet Analog i
Next-generation LCD fabs may trigger consolidation News & Analysis 4/2/2003 Post a comment
The growing number of Generation 5 and later LCD fabs will cause desktop LCD monitors and flat-panel TVs to continue dropping in price but likely will also give the upper hand to the top tier of suppliers.
That was the consensus of speakers at the DisplaySearch U.S. Flat Panel Display Conference in La Jolla, Calif., Tuesday.
Using PLLs to Obtain Carrier Synchronization: Part 2 Design How-To 4/2/2003 1 comment Impairments in digital communication channels cause frequency and phase offset headaches for designers. Through the use of PLLs, designers can improve carrier recovery in a receiver architecture and, in turn, combat impairments.

As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
January 2016 Cartoon Caption ContestBob's punishment for missing his deadline was to be tied to his chair tantalizingly close to a disconnected cable, with one hand superglued to his desk and another to his chin, while the pages from his wall calendar were slowly torn away.122 comments
