This session presents low-power RF designs targeting sensing and communication applications. The first paper introduces a mixer-first pulsed-LO beam-steering receiver enabling PLL-free operation with scalable power-performance trade-offs. The second paper presents a multi-source RF energy-harvesting IC with event-driven 3-D maximum power point tracking and SIMO regulation. The third paper reports a wideband active true-time-delay circuit achieving fine delay control for efficient self-interference cancellation in full-duplex systems. The final paper demonstrates a miniature LEO satellite localization tag using algorithm–hardware co-design to reduce required EIRP by 10 dB while achieving a highly compact integrated transmitter.
