Analog/Mixed-Signal, RF, Microwaves

Analog-mixed signal lab

Overview

This research cluster emphasizes synergistic cooperation and innovation amongst faculty members whose research focuses on various aspects of communication systems. The faculty in this research cluster are involved in system level protocols, system architecture and analysis, and implementation of communication systems as integrated circuits (ICs). IC technology is a key enabler in shrinking large systems into hand-held devices.

Faculty expertise includes analog, digital, and RF/microwave circuit design and devices, on-chip interconnect design and modeling, and package modeling including package-level antenna design. An effective top-down simulation and modeling methodology of communication systems is also being emphasized. Our research forms the basis for personal portable communication devices of today and of the future (such as the Dick Tracy watch!)

Research Facilities

Collaborative Research in Microelectronics (CRiME) Laboratory

The Collaborative Research in Microelectronics (CRiME) Laboratory is a fully equipped laboratory at Oregon State University for Communications/RF/mixed-signal research. It is housed in a 1,000 square feet facility. This laboratory is shared among faculty working in the simulation and design of RF/analog mixed-signal communication circuits and systems. The lab has a characterization facility that consists of computer-controlled instrumentation including DC to RF cascade probe stations, device characterization equipment (semiconductor parameter analyzer), mixed-signal circuit characterization equipment (oscilloscopes, RF signal sources, data acquisition, arbitrary waveform generator, logic analyzer), RF devices and circuit characterization equipment (26 GHz spectrum analyzer, 20 GHz network analyzer), and communications test equipment capable of generating almost all digital baseband and RF modulation schemes and performing bit-error-rate and communication channel measurements up to 26GHz. Additionally, the lab is equipped with a set of DSP development boards and core modules, microprocessor development boards and core modules, and a number of radio modules and antennas. All graduate students working in the mixed-signal and communication system area have Sun workstations at their desks. These facilities are sufficient for the faculty and students to fulfill the desired circuit and system-level research tasks.
