Harish Krishnaswamy, assistant professor of electrical
engineering at Columbia Engineering, has generated a record amount of power
output—by a power of five—using silicon-based nanoscale CMOS (complementary
metal oxide semiconductor) technology for millimeter-wave power amplifiers.
Power amplifiers are used in communications and sensor systems to boost power
levels for reliable transmission of signals over long distances as required by
the given application. Krishnaswamy’s research will be reported at the June
2013 Institute of Electrical and Electronics Engineers Radio Frequency
Integrated Circuits Symposium.
