Abstract:
Ultra-low power (ULP) transceivers are key subsystems for wireless sensor networks and Internet-of-Things (IoT), which impose stringent requirements of low cost (i.e., low silicon area), low power consumption, high sensitivity and tolerance to interferers. Recent receiver (RX) implementations achieve significant power reduction typically using sliding intermediate frequency (IF) and direct-conversion low-IF continuous-time (CT) architectures. To further reduce power consumption, we investigate a fully discrete-time (DT) high-IF RX architecture with complex-signaling band-pass filters (BPF) and a progressively reduced sampling rate, in which the IF frequency, fIF, is much greater than the signal bandwidth. An all-digital PLL employs a digitally controlled oscillator with switching current sources to reduce supply voltage and power without sacrificing its phase noise and startup margins. It also reduces 1/f noise allowing the ADPLL, after settling, to reduce its sampling rate or shut it off entirely during direct DCO data modulation. The switching power amplifier integrates its matching network while operating in class-E/F2 to maximally enhance its efficiency. The Bluetooth Low-Energy transmitter is realized in 28nm CMOS and satisfies all metal density and other manufacturing rules. It consumes a record low 3.6mW/5.5mW in TX/RX while delivering 0 dBm/3dBm RF power.
Biography:
R. Bogdan Staszewski received BSEE (summa cum laude), MSEE and PhD from University of Texas at Dallas, USA, in 1991, 1992 and 2002, respectively. From 1991 to 1995 he was with Alcatel in Richardson, Texas. He joined Texas Instruments in Dallas, Texas in 1995. In 1999 he co-started a Digital RF Processor (DRP) group in TI with a mission to invent new digitally intensive approaches to traditional RF functions. Dr. Staszewski served as a CTO of the DRP group between 2007 and 2009. In July 2009 he joined Delft University of Technology in the Netherlands where he is currently a part-time Full Professor. Since Sept. 2014 he is a Full Professor at University College Dublin (UCD) in Ireland. He has co-authored two books, four book chapters, 220 journal and conference publications, and holds 160 issued US patents. His research interests include nanoscale CMOS architectures and circuits for frequency synthesizers, transmitters and receivers. He is an IEEE Fellow and a recipient of IEEE Circuits and Systems Industrial Pioneer Award (http://ieee-cas.org/about/awards/industrial-pioneer-award).
