Peregrine Semiconductor - RF CMOS

A fabless provider of high-performance radio frequency integrated circuits, or RFICs. Thier innovation called UltraCMOS makes the integration of multiple RF, mixed-signal, and digital functions on a single chip.

Peregrine Semiconductor - RF CMOS

They provide solutions for WCDMA and GSM digital cellular, broadband, DTV, DVR, and radiation hard space and defense programs.

The products are used in applications like ...

"From GSM cellular handsets, CDMA digital cellular and RIM devices, to CATV/DTV/DVR and other high-growth wireless broadband applications .."

Peregrine PE97022 high-performance integer-N PLL

Peregrine's PE97022 is a high-performance integer-N PLL capable of frequency synthesis up to 3.5 GHz. Features a 10/11 dual modulus prescaler, counters and a phase comparator.

"The TX/RX portion of the RF signal chain lies between the tuning/switching portion and any sort of power conversion components. This portion of the signal chain has potential for size reduction and increased efficiency...."

Jim Svoboda - Interactive Examples and Exercises

James A. Svoboda - ECE Department, Clarkson University has created numerous interactive examples throughout the textbook - Introduction to Electric Circuits. Interactive Examples made of Java Applets.

Interactive Examples and Exercises - Jim Svoboda

The Interactive Exercise shown here considers a similar, but different, circuit. Like the Interactive Example, the Interactive Exercise poses a problem, then accepts and checks the user's answer. Student learning is further supported by extensive help, in the form of worked example problems, available from within the Interactive Exercise using the “Worked Example” button.

Circuit Design Lab

The Circuit Design Lab consists of several Java applets, each providing an opportunity to experiment with the design of a particular circuit:

Variations of this problem are obtained using the “New Problem” button. We can peek at the answer using the “Show Answer” button. The Interactive Example and Exercises provide hundreds of addition practice problems with countless variations, all with answers that are checked immediately by the computer.
