With the advent of small mobile internet devices (MIDs) and a rising consumer demand for multiple simultaneous transmit and receive communication links, the need for highly programmable, low-cost transceiver front-ends that co-exist with other radios on the same platform or die, has increased. For the past decade, CMOS technologies have demonstrated the ability to integrate the entire transceiv...

We present a high-speed, clockless, serial link transceiver for inter-chip communication in asynchronous VLSI systems. Serial link transceivers achieve high offchip data rates by using multiplexing transmitters and demultiplexing receivers that interface parallel on-chip data paths with high-speed, serial off-chip buses. While synchronous transceivers commonly use multi-phase clocks to control ...

A fully integrated system-in-package (SiP) for UHF (860– 960MHz) RFID mobile reader is presented. The SiP is made up of an UHF transceiver, a power amplifier (PA), and two baluns. The UHF transceiver was designed in TSMC 0.18μm Si CMOS and the PA was developed with InGaP/GaAs hetero-junction-bipolar transistor (HBT) technology. The transceiver IC is fully integrated for mobile UHF RFID applicat...

CMOS RF has evolved from a novelty to a necessity with the mergence of all analog and digital functionality into a single chip for standards such as Bluetooth and WLAN/802.11. The stringent performance requirements associated with cellular standards such as GSM, however, has either limited the level of RF transceiver integration, or compelled the use of alternative technologies such as BiCMOS o...

A Non‐Uniform Discrete Multitone (DMT) transceiver employing an octave spaced quadrature mirror filter (QMF) bank, can be used to overcome the problem of channel noise enhancement in the zero‐ forcing (ZF) equalization technique. In this letter, performance of the Non‐Uniform DMT system is analyzed. A study of the crosstalk between sub‐channels due to non‐ideal filter banks is also presented. C...

This paper presents a 5-300MHz multi-nuclei NMR transceiver designed with spectroscopy for drug discovery in mind. The overall transceiver (transmitter and receiver), is implemented in 130nm CMOS, occupies an active area of 2mm and consumes 12mA from a 1.5V supply. The measured phase noise for the on-chip frequency synthesizer is -110dBc at 10KHz offset when the LO frequency is 212.966MHz (∼H L...

We present robust joint nonlinear transceiver designs for multiuser multiple-input multiple-output (MIMO) downlink in the presence of imperfections in the channel state information at the transmitter (CSIT). The base station (BS) is equipped with multiple transmit antennas, and each user terminal is equipped with one or more receive antennas. The BS employs TomlinsonHarashima precoding (THP) fo...

An optimization procedure for the location of the relay transceiver in ultrawideband wireless communication system is presented. The impulse responses of different transceiver locations are computed by shooting and bouncing ray/image (SBR/Image) techniques and inverse fast Fourier transform (IFFT). By using the impulse responses of these multi-path channels, the bit error rate (BER) performance...
