Abstract:

Maintaining high level of signal integrity in RF front-end is becoming very important due to the explosive growth of mobile devices. On top of interference from other wireless devices, FDD systems suffers from the interference within the transceiver as a result of the Transmitter (TX) leakage to the Receiver (RX). In the presence of a strong jammer near  RX band, the TX leakage modulation is transferred, due to RX nonlinearities, to the jammer and widens its spectrum causing contamination of the signal. The phenomena is called cross modulation distortion (XMD).  Solution to these problems are needed in both commercial and defense applications and are being investigated.

Farooq Amin received the B.S. and degree in computer engineering from COMSATS IIT, Pakistan in 2005, and the M.S. degree in electrical engineering from Linköping University, Linköping, Sweden, in 2009. He is currently working towards the Ph.D. degree in electrical engineering at Virginia Tech, Blacksburg, Virginia. From 2005 to 2007, he was with COMSATS IIT, Pakistan as a lecturer and contributed in establishing the VLSI Lab. From 2011 to 2013, he was with the CPU design team at Intel Corp. Hillsboro, OR, where he was involved with the design of Intel Haswell/Broadwell family of microprocessors. His research interests includes RF front-ends, analog front-end for X-ray detectors, PLL, low power custom digital IC design, and arithmetic circuits.
