In general, Ocean Tomo, a part of J.S. Held, can provide analysis of the following products:
- RF transceivers
- RF Power amplifiers
- Connectivity Solutions (Bluetooth, WiFi, etc)
- Power management ICs
- Analog products in general
In conjunction with our wireless live and emulator-based testing capabilities and system level firmware analysis, circuit analysis of RF and analog components provides a comprehensive solution to our clients’ intellectual property challenges by revealing details of any circuit blocks of interest.
Circuit analysis techniques cover a broad range of RF and analog specific features: identifying major circuit components such as inductors and capacitors, analyzing high level architecture of a target device using overall die construction and floor plan, and extracting detailed circuit blocks of interest and analyzing their operation and functionality.
Whether it is a power amplifier with different frequency bands, low noise amplifier (LNA), local oscillator (LO), analog to digital converter (ADC) digital to analog converter (DAC), or clock synthesizers, we have the capability to extract circuit elements and construct hierarchical circuit schematics and analyze the extracted circuits.
Comparing a current product of interest with a previous generation or other variants often provides a cost-effective way of preparing evidence of use documents in cases where previous analysis data exists. We apply the most cost- effective analysis techniques and methodologies to provide economic solutions to our clients. Selective delayering of areas of interest, followed by imaging and comparison of images would be one of the approaches that could be used in such cases.
Recent analysis projects involve devices from major wireless and RF product manufacturers. They include Bluetooth and WiFi integrated wireless connectivity solutions used by multiple global smartphone manufacturers, several generations of wireless RF/baseband, and applications processors products adopted by one of largest smartphone manufacturers, to name a few.
Functional testing often provides a good alternative or complementary analysis solution to certain RF and analog patent problems. Evaluating power consumption characteristics over different operating conditions using our in- house wireless testing capability and power measurement capabilities of battery powered smartphones proved to be very efficient and cost effective to support certain patents which would have been a huge challenge if only circuit analysis was considered.
Datasheets and other product documents-based analysis are an important component of providing analog and RF device related support for patent related analysis.
Our RF and analog product analysis expertise is a well-organized and practical, yet comprehensive, combination of complementary analysis capabilities including circuit analysis, process analysis, imaging, and system level testing capabilities and datasheet analysis. The result is more cost effective and efficient solutions for our customers.
