This book describes numerous situations that graduate students will COMMONly encounter as they work towards the goal of earning their PhD. Starting from your very first day in the lab, to the beginning stages of your post-PhD job search, to writing your dissertation,we’ve tried to offer you sage advice on how to handle particular situations as they arise.

Abstract: Class D amplifiers are typically very efficient, making them ideal candidates for portable applications that require longbattery life and low thermal dissipation. However, electromagnetic interference (EMI) is an issue that COMMONly accompanies theClass D switching topology. Active-emissions limiting reduces radiated emissions and enables "filterless" operation, allowingdesigners to create small, efficient portable applications with low EMI.

Photodiodes can be broken into two categories: largearea photodiodes with their attendant high capacitance(30pF to 3000pF) and smaller area photodiodes withrelatively low capacitance (10pF or less). For optimalsignal-to-noise performance, a transimpedance amplifi erconsisting of an inverting op amp and a feedback resistoris most COMMONly used to convert the photodiode currentinto voltage. In low noise amplifi er design, large areaphotodiode amplifi ers require more attention to reducingop amp input voltage noise, while small area photodiodeamplifi ers require more attention to reducing op amp inputcurrent noise and parasitic capacitances.

In industrial applications, high voltage power supply spikes with durations ranging from a few microseconds to hundreds of millisecondsare COMMONly encountered. The electronics in these systems must not only survive transient voltage spikes, but in many cases alsooperate reliably throughout the event.

The LT®1943 is a highly integrated, 4-output regulatordesigned to power large TFT LCD panels. The LT1943employs switching regulators—instead of linear regulators—to minimize power dissipation and accommodate awide input voltage range. The wide input range, 4.5V to22V, allows it to accept a variety of power sources,including the COMMONly used 5V, 12V and 19V AC adaptors.

Low power standby requirements are typically associatedwith battery-powered systems. Automotive systems,for example, COMMONly require power supplies tomaintain output voltage regulation even under no-loadconditions—while drawing minimal quiescent current topreserve battery life. Rising energy costs, however, haveextended the need for low current standby operation toline-powered systems, such as small plugged-in appliancesfor home and business.

Consumer display applications COMMONly use high-speed LVDS interfaces to transfer videodata. Spread-spectrum clocking can be used to address electromagnetic compatibility (EMC)issues within these consumer devices. This application note uses Spartan®-6 FPGAs togenerate spread-spectrum clocks using the DCM_CLKGEN primitive.

Abstract: This application note illustrates the flexibility of the MAX7060 ASK/FSK transmitter. While the currently available evaluationkit (EV kit) has been optimized for the device's use in a specific frequency band (i.e., 288MHz to 390MHz), this document addresseshow the EV kit circuitry can be modified for improved operation at 433.92MHz, a frequency COMMONly used in Europe. Twoalternative match and filter configurations are presented: one for optimizing drain efficiency, the other for achieving higher transmitpower. Features and capabilities of earlier Maxim industrial, scientific, and medical radio-frequency (ISM-RF) transmitters areprovided, allowing comparison of the MAX7060 to its predecessors. Several design guidelines and cautions for using the MAX7060are discussed.
