The second volume in the Write Great Code series Supplies the critical information that today s computer science students don t often get from college and university courses: How to carefully choose their high-level language statements to produce efficient code. Write Great Code, Volume 2: Thinking Low-Level, Writing High-Level, teaches software engineers how compilers translate high-level language statements and data structures into machine code. Armed with this knowledge, a software engineer can make an informed choice concerning the use of those high-level structures to help the compiler produce far better machine code--all without having to give up the productivity and portability benefits of using a high-level language

For many years prior to the 1970s, engineers designed and built switch mode power Supplies (SMPSs) using methods based largely on intuitive and exper- imentally derived techniques. In general, these power Supplies were able to achieve their primary goal of high-efficiency power conversion; unfortu- nately, due to the lack of adequate theoretical analysis techniques, many of these power Supplies only marginally met their desired performance require- ments. In many cases, they were considered to be unreliable.

The trend in ADCs and DACs is toward higher speeds and higher resolutions atreduced power levels. Modern data converters generally operate on ±5V (dualsupply) or +5V (single supply). In fact, many new converters operate on a single +3Vsupply. This trend has created a number of design and applications problems whichwere much less important in earlier data converters, where ±15V Supplies and ±10Vinput ranges were the standard.

OPTOELECTRONICS CIRCUIT COLLECTION AVALANCHE PHOTODIODE BIAS SUPPLY 1Provides an output voltage of 0V to +80V for reverse biasingan avalanche photodiode to control its gain. This circuit canalso be reconfigured to supply a 0V to –80V output.LINEAR TEC DRIVER–1This is a bridge-tied load (BTL) linear amplifier for drivinga thermoelectric cooler (TEC). It operates on a single +5Vsupply and can drive ±2A into a common TEC.LINEAR TEC DRIVER–2This is very similar to DRIVER–1 but its power output stagewas modified to operate from a single +3.3V supply in orderto increase its efficiency. Driving this amplifier from astandard +2.5V referenced signal causes the output transistorsto have unequal power dissipation.LINEAR TEC DRIVER–3This BTL TEC driver power output stage achieves very highefficiency by swinging very close to its supply rails, ±2.5V.This driver can also drive ±2A into a common TEC. Operationis shown with the power output stage operating on±1.5V Supplies. Under these conditions, this linear amplifiercan achieve very high efficiency. Application ReportThe following collection of analog circuits may be useful in electro-optics applications such as optical networkingsystems. This page summarizes their salient characteristics.

Integrated EMI/Thermal Design forSwitching Power SuppliesWei ZhangThesis submitted to the Faculty of theVirginia Polytechnic Institute and State Universityin partial fulfillment of the requirements for the degree of Integrated EMI/Thermal Design forSwitching Power SuppliesWei Zhang(ABSTRACT)This work presents the modeling and analysis of EMI and thermal performancefor switch power supply by using the CAD tools. The methodology and design guidelinesare developed.By using a boost PFC circuit as an example, an equivalent circuit model is builtfor EMI noise prediction and analysis. The parasitic elements of circuit layout andcomponents are extracted analytically or by using CAD tools. Based on the model, circuitlayout and magnetic component design are modified to minimize circuit EMI. EMI filtercan be designed at an early stage without prototype implementation.In the second part, thermal analyses are conducted for the circuit by using thesoftware Flotherm, which includes the mechanism of conduction, convection andradiation. Thermal models are built for the components. Thermal performance of thecircuit and the temperature profile of components are predicted. Improved thermalmanagement and winding arrangement are investigated to reduce temperature.In the third part, several circuit layouts and inductor design examples are checkedfrom both the EMI and thermal point of view. Insightful information is obtained.

This document presents design techniques and reference circuits that power Virtex™-4 FXRocketIO™ multi-gigabit transceivers (MGTs) operating at data rates below 3.125 Gb/s.When using multiple transceivers, it is sometimes preferred to power them from a switchingpower supply. However, switching power Supplies generate noise that affects transceiver
