Highly-Integrated Low-Power RF Receivers for Distributed Sensing and IoT Devices

Creator:: Bialek, Hayden
Abstract:: Low-power receivers (RX) with 100$\mu W$-scale power consumption can enable several power/energy-constrained IoT applications. However, achieving sensitivity, interferer tolerance and wide operating range with low power presents a challenge for existing architectures, particularly those constrained to highly integrated solutions without high-Q off-chip components. Existing solutions rely heavily on high quality...

Co-channel Blocker and Self-Interferer Tolerant Receiver Architectures for MIMO and Full-Duplex MIMO Receivers

Creator:: Jain, Sanket
Abstract:: This research focuses on receiver architectures which enable better spectral eciency by handling blockers in the same spectral range as the signal. The presence of such blockers, without the use of blocker cancelling/ltering techniques leads to gain compression and hence, consequent performance degradation of receivers leading to reduced spectrum...

Real Time Self-Interference Cancellation for Wireless Transceivers

Creator:: Taylor, Daniel N.
Abstract:: With the need for higher spectral efficiency and data rates the rise of simultaneous transmit-and-receive (STAR) radios is becoming increasingly valuable. While many systems employ two separate channels for transmit and receive to double the data speed, this comes at the cost of doubling the RF band. This same performance...
