SAN JOSE, Calif. -- Cypress Semiconductor Corp. (Nasdaq: CY) today introduced a new PSoC® programmable system-on-chip that simplifies the design of next-generation industrial, home appliance and consumer systems that require multiple sensors. Many Internet of Things (IoT) applications require multiple sensors and can benefit from dedicated coprocessors that offload sensor processing from the host and reduce overall system power consumption. The new PSoC Analog Coprocessor integrates programmable analog blocks, including a new Universal Analog Block (UAB), which can be configured with GUI-based software components. This combination simplifies the design of custom analog front ends for sensor interfaces by allowing engineers to update sensor features quickly with no hardware or host processor software changes, while also reducing BOM costs.
For example, in home automation applications, engineers can easily configure the PSoC Analog Coprocessor to continuously monitor multiple sensors, such as temperature, humidity, ambient light, motion and sound, allowing the host to stay in a standby low-power mode. Future design changes to support new sensor types can also be easily implemented by reconfiguring the programmable analog blocks. Cypress will demonstrate the PSoC Analog Coprocessor, along with its PSoC, FM Flexible MCU, Bluetooth® Low Energy and Energy Harvesting Power Management IC solutions at Sensors Expo from June 21 to 23 in booth 416 at the McEnery Convention Center in San Jose. More information on the PSoC Analog Coprocessor is available at www.cypress.com/PSoCAnalog.[Continue reading →]

Microchip’s newest AFEs improve application performance with their industry-leading accuracy, high integration and optimal number of channels for single-phase energy measurement. Additionally, the high AFE accuracy facilitates energy-meter calibration, which reduces production costs.[Continue reading →]
When designers are trying to select a component in the signal path of a satellite system, it is often difficult to find a device with both the radiation tolerance and accuracy required. Signal integrity is, after all, the key specification when designing an analog signal chain. The main causes of error to the integrity of the signal chain can be divided into two categories: inaccuracies due to noise and inaccuracies due to shifts in voltage. While it is important to consider all components in the signal path, one component is the most critical in achieving precision performance: the voltage reference.[Continue reading →]

Increased competition, more dense designs and integration of different technologies in a small space combined with market regulatory pressures are creating new challenges for original equipment manufacturers. As a result, implementing the necessary transient immunity protections to prevent application malfunction due to transients on power and signal lines is becoming ever more challenging. The impact of increasing microcontroller (MCU) sensitivity and low-cost application design is being felt in all markets: consumer, industrial, automotive, etc. While there are significant differences in the design and use of products for these markets, the susceptibilities induced in all microcontroller-based applications are essentially the same. Typical susceptibilities include unexpected state changes on input pins (reset, interrupt request, or general purpose inputs) and corruption of on-chip clock signals, which can all cause various operational issues on the design itself, in addition to resulting in failure to meet regional compliance regulations for electromagnetic compatibility (EMC).[Continue reading →]
This White Paper describes the implementation of the Rohde & Schwarz (R&S) FSVR’s realtime capabilities. It shows fields of application as well as the technical implementation. The measurement speed available in today's spectrum analyzers is the result of a long evolution. But one property has survived all evolution steps: even the R&S FSV does not detect signals between the end of one sweep and the start of the next one. This gap in data acquisition, the so called "blind time", has decreased with each new spectrum analyzer generation, but it is still present.
The keys to a real-time spectrum analyzer are: · Parallel sampling and FFT calculation: The data acquisition continues while the FFTs are performed. · Fast processing of FFT algorithms: The computation speed must be high enough to avoid that "stacks" of unprocessed data are being built up. Slow FFT computation will result in an overflow of the capture memory and a subsequent data loss (= a new blind time).[Continue reading →]

The 23rd annual Hot Chips conference at Stanford University held a series of talks that were billed as a "tutorial" on Package-Scale Power Management. In actuality, the talks were less tutorial and more of a review of the challenges, and current and (potential) future solutions for power management in heterogeneous multicore designs. One common thread that ran through each of the presentations... integration of more complex and higher performance analog circuits is an absolute requirement. Digital needs analog more than ever.

Daniel explains why wireless and medical imaging systems cannot simply appropriate data compression technologies, such as MP3, used in other fields, elaborating on why compression technologies fall short for higher-performance applications. He then describes a new compression algorithm that can keep pace with sample rates of up to 40 gigasamples per second.Today’s Data Acquisition Systems (DAS) using Analog-to-Digital Converters (ADCs) in wireless infrastructure and medical imaging applications are adding more channels while at the same time increasing both bit-resolutions and sampling rates, causing a data explosion at the system level. All this data must be transported from the DAS, where it is acquired, to processing devices such as FPGAs or CPUs, where the raw data is processed. This “data pipe” uses many device I/Os, crosses various interfaces and busses, and often includes different forms of storage along the way such as DRAM or disk drives and RAID. Over the years, the brute force approach to increasing the size and capacity of this pipe was to throw more hardware at the problem. Indeed, ADCs grew wider in bits; FPGAs grew larger in density, and memory requirements increased accordingly, with the same thing happening to a lesser extent in I/O as well. Systems grew more complex, used more power, and saw overall higher bill of material costs.
Dealing with this data explosion without increasing complexity and cost in FPGA-based designs means adopting some form of data compression in the FPGA, usually with IP algorithms. Real-time signal compression of the data sampled in systems such as wireless and medical imaging can take on the data geyser, at the same time reducing system complexity, power, and costs.[Continue reading →]
