Conference paper (peer-reviewed)abstract
- A 3.5GHz 8-phase all-digital clock generator is fabricated in 150nm CMOS to achieve scalable 1.7x frequency-range and 9ps end-to-end time resolution measured at 1.6V and 110°C. A closed-to-open loop control scheme enables 32mW open-loop power consumption, 300μW at clock gate-off, zero-cycle response during clock re-enable, and

Conference paper (peer-reviewed)abstract
- A low-phase-noise low-phase-error 1.8 GHz quadrature CMOS VCO was presented. The VCO with three metal layers showed -140 dBc/Hz or less phase noise across an 18% tuning range while drawing 25 mA from a 2 V power supply. The VCO showed high phase-noise figure-of-merit and low phase-error.

A remote-powered RFID tag with 10Mb/s UWB Uplink and -18.5dBm sensitivity UHF downlink in 0.18μm CMOS
- 2009
-
In: Digest of technical papers / IEEE International Solid-State Circuits Conference. - 0193-6530. ; , s. 198-199,199a
-
Journal article (peer-reviewed)abstract
- In this work, a 10 Mb/s impulse UWB RFID tag in 0.18 mum CMOS is presented. The tag is remotely powered by a UHF signal with a minimum input RF power as low as 14.1 muW. The primary innovation is to employ two different communication links (UWB and UHF) respectively in the uplink and downlink of the tag. This is because the amount of data or instructions from a reader to a tag is small and as a result a conventional UHF-RFID link at 900MHz can be used as the downlink. The UHF signal also provides remote power to the tag. The uplink requires higher data rates and precise positioning capability therefore an l-UWB transmitter is employed.

A compact CMOS MEMS microphone with 66dB SNR
- 2009
-
In: [Host publication title missing]. - 0193-6530. ; 52, s. 350-351
-
Conference paper (peer-reviewed)abstract
- A microphone system, comprising two differentially-operated MEMS microphones and a CMOS differential amplifier mounted on a common die substrate, has a very small volume of 2.6x3.2x0.865mm3, showing a record-high SNR of 66dB over the 20Hz-20kHz audio band. The system sensitivity is -33.5dB (Vrms/Pa), PSRR is above 55dB, and THD is below 1% for sound pressure levels below 112dB. The current consumption is 120μA from a 1.8V power supply.

A 2.4-to-5.3GHz Dual-Core CMOS VCO with Concentric 8-Shaped Coils

Conference paper (peer-reviewed)abstract
- Despite recent attempts to relax the phase-noise demands on voltage-controlled oscillators (VCOs) for cellular communications [1], mainstream radios require harmonic VCOs capable of a very low phase noise with moderate power consumption, associated to a large tuning range (TR) and a high insensitivity to interfering signals. Ideally, the TR should be in excess of one octave, since this allows the easy synthesis of all frequencies below those directly generated by the VCOs via repeated frequency divisions by 2. At the same time, the oscillation spectrum should be affected as little as possible by spurious (common-mode) magnetic fields impinging on the inductor coil in the VCO tank. This is a crucial requirement in modern radios, where there are more PLLs active at the same time, and particularly when (non-contiguous) carrier aggregation is implemented, since in this case the signal bands may be very close to each other. If an individual PLL is used for each band, the VCOs may oscillate very close to each other, or at frequencies that are harmonically related to each other, posing a very serious issue of mutual pulling through the respective magnetic field. And even if a single VCO is used [2], or two (or more) VCOs that are not harmonically related [3], it is nevertheless a good practice to design the tank inductor as insensitive as possible to external magnetic fields, which abound in and close to the radio IC.

A 9-band WCDMA/EDGE transceiver supporting HSPA evolution
- 2011
-
In: [Host publication title missing]. - 0193-6530. ; , s. 366-368
-
Conference paper (peer-reviewed)abstract
- The future of cellular radio ICs lies in the integration of an ever-increasing number of bands and channel bandwidths. This paper presents a transceiver together with the associated discrete front-end components. The transceiver supports 4 EDGE bands and 9 WCDMA bands (l-VI and Vlll-X), while the radio can be configured to simultaneously support the 4 EDGE bands and up to 5 WCDMA bands: 3 high bands (HB) and 2 low bands (LB). The RX is a SAW-less homodyne composed of a main RX and a diversity RX. To reduce package complexity with so many bands, we chose to minimize the number of ports by using single-ended RF interfaces for both RX and TX. This saves seve ral package pins, but requires careful attention to grounding. The main RX has 8 LNA ports and the diversity RX has 5, with some LNAs supporting multiple bands. On the TX side, 2 ports are used for all EDGE bands and 4 for the WCDMA bands.
