—The unlicensed band around 60 GHz can be utilized for wireless communications at data rates of several gigabits per second. This paper describes a receiver front-end that incorporates a folded microstrip geometry to create resonance at 60 GHz in a common-gate LNA and active mixers. Realized in 0.13-m CMOS technology, the receiver front-end provides a… (More)

— This paper presents a study of phase noise in two inductorless CMOS oscillators. First-order analysis of a linear oscillatory system leads to a noise shaping function and a new definition of Q. A linear model of CMOS ring oscillators is used to calculate their phase noise, and three phase noise phenomena, namely, additive noise, high-frequency… (More)

—Injection locking characteristics of oscillators are derived and a graphical analysis is presented that describes injection pulling in time and frequency domains. An identity obtained from phase and envelope equations is used to express the requisite os-cillator nonlinearity and interpret phase noise reduction. The behavior of phase-locked oscillators… (More)

—A 10-Gb/s phase-locked clock and data recovery circuit incorporates an interpolating voltage-controlled oscillator and a half-rate phase detector. The phase detector provides a linear characteristic while retiming and demultiplexing the data with no systematic phase offset. Fabricated in a 0.18-m CMOS technology in an area of 1 1 0 9 mm 2 , the circuit… (More)

This paper describes precision techniques for the design of comparators used in high-performance analog-to-dig-ita1 converters employing parallel conversion stages. Following a review of conventional offset cancellation techniques, circuit designs achieving 12-b resolution in both BiCMOS and CMOS 5-V technologies are presented. The BiCMOS comparator… (More)

—A triple-resonance network increases the band-width of cascaded differential pairs by a factor of 2 3, yielding a 40-Gb/s CMOS amplifier with a gain of 15 dB and a power dissi-pation of 190 mW from a 2.2-V supply. An ESD protection circuit employs negative capacitance along with T-coils and pn junctions to operate at 40 Gb/s while tolerating 700–800 V.

—A large-signal piecewise-linear model is proposed for bang-bang phase detectors that predicts characteristics of clock and data recovery circuits such as jitter transfer, jitter tolerance, and jitter generation. The results are validated by 1-Gb/s and 10-Gb/s CMOS prototypes using an Alexander phase detector and an LC oscillator.

—A modification of stacked spiral inductors increases the self-resonance frequency by 100% with no additional processing steps, yielding values of 5 to 266 nH and self-resonance frequencies of 11.2 to 0.5 GHz. Closed-form expressions predicting the self-resonance frequency with less than 5% error have also been developed. Stacked transformers are also… (More)

—A discrete-time analog echo canceller is described that reduces the echo in the front end of Gigabit Ethernet twisted-pair interfaces. Echo cancellation in the analog domain by means of four taps reduces the complexity of the digital echo canceller and crosstalk cancellers. Designed in a 0.4-m CMOS technology, the circuit employs an LMS algorithm to adapt… (More)
