Battery Charge Control: Dedicated ICs vs Microcontrollers Design How-To 10/25/2011 3 comments Microcontrollers can be used to directly control battery charger power conversion circuits. However, microcontroller circuits and firmware are normally more expensive to design and test and often cost more to produce than chargers based on dedicated charge control ICs. Here are the tradeoffs to consider when making a choice between microcontrollers and dedicated charge control ICs for battery charge control.
Got a Linear Rocks ticket? News & Analysis 10/20/2011 18 comments Linear Technology is built on its founders’ undying belief in analog, its mission carried out by hundreds of analog “gurus” at the company. Of course, if you have a ticket to Linear’s 30th anniversary party, you already knew that.
Infineon to make power ICs on 300-mm wafers News & Analysis 10/12/2011 6 comments Infineon Technologies AG has succeeded in making power MOSFETs on thinned 300-mm wafers and is planning to invest 250 million euro (about $340 million) to set up manufacturing in Dresden, Germany.
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.
