dc.description.abstract	More than 100 billion devices are expected to be connected wirelessly by 2020 as expected from the Internet of Things (IoT) and 5G deployments. Reconfigurability and sustainable power consumption are two of the major concerns to cope up with the expected changes. In the light of the above challenges, two low-power, frequency agile and broadband radio receiver architectures, namely, the six-port receiver (SPR) and the N-path passive mixer (P-M) receiver, have been explored in this thesis. First, a complexity reduced calibration approach for the SPR is developed that would reduce the power consumption of the SPR system. After analyzing the advantages and drawbacks of the SPR and the N-path P-M receiver architectures, a new quadrature phase shift frequency selective (QPS-FS) receiver architecture is proposed that attempts to retain the advantages of both the existing architectures while it tries to eliminate or minimize their drawbacks. The proposed QPS-FS receiver is a frequency selective architecture in which the desired band RF signal at the signal carrier frequency equal to the local oscillator clock frequency is frequency down-converted and quadrature (I/Q) demodulated while the in- and out-of-band blocker and interferer signals are reflected and collected that could be used for energy harvesting purposes. The thesis culminates in the proposal and implementation of a novel broadband, frequency reconfigurable, low power, blockers and system impairments tolerant energy harvesting radio receiver architecture that is frequency selective, concurrently utilizing the in-band RF signal for information decoding and the in- and out-of-band blocker and interferer signals for energy harvesting for increased battery-life or self-sustainable operation of the receiver system.	en_US
