New Step-Down Regulator Protects DSPs/FPGAs from Harmful Transient Voltage Spikes New!
High performance DSPs, FPGAs, and microprocessors require high quality power supply rails to ensure there are no logic malfunctions over the full range of system operating conditions. In selecting a dc-to-dc regulator, it is vital that the output voltage tolerance does not fall outside the limits of the load (DSP, FPGA, etc.). Critical parameters, such as output accuracy and line and load regulation, are specified and the transient response of the supply should be reviewed to ensure the output voltage is contained within system limits.

Ultrabroadband PLL with Integrated Low Noise VCO Covers All Cellular Bands New!
A long time challenge for RF designers has been the need to develop an LO synthesizer that is both high performance and highly adaptable and reconfigurable. Traditionally, RF designers have sought to optimize the loop filter in order to find a suitable trade-off between phase noise, spurious signals, and lock time. This approach often resulted in synthesizer designs that were highly band specific and, therefore, not easily reconfigurable. This approach resulted in longer design cycle times, longer time to market, and more unwieldy BOM structures - hence, more difficult production logistics and supply chain challenges.

Phase Response in Active Filters, Part 2: Low-Pass and High-Pass Responses New!
A previous article examined the relationship of the filter phase to the topology of its implementation. This article will examine the phase shift of the filter transfer function itself. While filters are designed primarily for their amplitude response, the phase response can be important in applications such as time delay simulation, cascaded filter stages, and especially process-control loops.

The Basics of Video Decoders in Supervision and Inspection New!
Video cameras - which range from inexpensive, low-definition black-and-white closed-circuit television systems to state-of-the-art high-definition digital-video systems - are found in diverse applications including product inspection, traffic monitoring, and real-time face recognition. Dropping unneeded data and passing only the essential parts of the picture can simplify the video system - saving memory and computational cycles.

Tiny Difference Amps: small size, small price, big performance New!
Analog Devices, Inc.introduced three new low-power difference amplifiers as small as 4.9 mm x 3 mm and featuring slew rates up to 10 times faster than competing products. Designed for high-performance, power-critical applications, the AD8276, AD8277and AD8278 difference amplifiers are half the size of competing devices and much smaller than discrete alternatives consisting of resistor arrays and operational amplifiers. The amplifiers also eliminate the added expense and design overhead associated with complex peripheral protection circuitry.

Analog Clocking ICs replace expensive, high-frequency VCOS; improve jitter New!
Analog Devices, Inc.expanded its clock-product portfolio with the launch of the AD9552 oscillator frequency upconverter and the AD9547 clock synchronizer. Both products streamline system designs and reduce implementation comfplexity and cost while improving jitter performance.

Some Chips Have Moving Parts! New!
Q. Is it true that over the years electrical devices have evolved to where they have no moving parts at all?
A. While it is true that any machinery becomes more reliable as the number of moving parts where friction can cause wear is reduced, there are actually integrated circuits (ICs) which only work because of moving parts on the surface of the chip. (View full article)

Which carries more weight, a datasheet or SPICE macromodel? New!
Q. When running a SPICE (Simulation Program with Integrated Circuit Emphasis) simulation with one of your amplifier models, I get different results than those shown in the datasheet. Which should I believe?
A. This is one case where we'd rather not have any variety in our lives. In fact, what we're really after is monotony and consistency when it comes to SPICE models and datasheets...(View full article)
