Milpitas, Calif. -- California Micro Devices Corporation (CMD) introduced a new technology for providing high-value passive solutions to Pentium, Pentium Pro and telecommunication board level systems. It allows the combination of thin film passive components such as resistors and capacitors with active semiconductor components such as diodes, charge pumps, voltage references, operational amplifiers, analog multiplexers, mixed signal elements, and logic circuits. Unlike traditional thick film passive component manufacturing which uses ceramic material for the chip substrate, CMD's process uses silicon wafer semiconductor manufacturing technology. CMD's patented processes produce a range of application specific network components with significant size reduction and performance benefits for desktops, servers, notebooks, cellular communication, networking, and portable communication devices. California Micro Devices calls these product solutions "P/Active" or "PAC" to denote the combination of passive and active circuitry. The new technology can address multiple challenges created in modern circuitry. For example, P/Active can be applied to circuits such as SCSI terminators where precision and higher performance termination networks need to be combined with active switching circuitry while providing a voltage source. P/Active technology also provides the benefits of higher frequency operation to 3 GHz and above, precision ratio matching, built-in electrostatic discharge (ESD) protection above 2,000 volts, low voltage requirements, and integration of low current active circuits. Products will be offered in industry standard surface mount packages.
