Healthcare at Home (Part II)
A major trend in medicine is to move treatments and monitoring out of the hospital or even the doctor's office and either attach them to the patient or enable it to be done in the home. What can device designers do to aid this effort and what technologies would help to enable it.

ADIsim Design/Simulation Tools (2)

ADIsimPLL™- Version 3.43
ADIsimPLL enables the rapid and reliable evaluation of new high performance PLL products from ADI. It is the most comprehensive PLL Synthesizer design and simulation tool available today. Simulations performed include all key non-linear effects that are significant in affecting PLL performance. ADIsimPLL removes at least one iteration from the design process, thereby speeding the design- to-market.
ADIsimRF
ADI’s ADIsimRF design tool provides calculations for the most important parameters within the RF signal chain, including cascaded gain, noise figure, IP3, P1dB, and total power consumption.
