Time-to-digital converters (TDCs) are vital components in time and distance measurement
and frequency-locking applications. There are many architectures for implementing TDCs …

Time-to-digital converters (TDCs) are increasingly used as building blocks in biomedical
imaging, digital communication, and measurement instrumentation systems. When …

On the basis of a generic mixed-signal system the scaling difficulties of analog and mixed-
signal circuits based on a signal representation in the voltage domain are discussed for …

We present the first all-digital PLL and polar transmitter for mobile phones. They are part of a
single-chip GSM/EDGE transceiver SoC fabricated in a 90 nm digital CMOS process. The …

A system on a chip (SoC) includes a transceiver comprising a transmitter having a power
amplifier and a receiver having a signal buffer. At least one of the transmitter and receiver …

A steady trend towards the design of mostly-digital and digital-friendly analog circuits,
suitable to integration in mainstream nanoscale CMOS by a highly automated design flow …

A voltage-controlled oscillator (VCO) based analog-to-digital converter (ADC) is a time-
based architecture with a first-order noise-shaping property, which can be implemented …

This paper introduces a ΔΣ fractional-N digital PLL based on a single-bit TDC. A digital-to-
time converter, placed in the feedback path, cancels out the quantization noise introduced …

After being the subject of speculation for many years, a software-defined radio receiver
concept has emerged that is suitable for mobile handsets. A key step forward is the …

A broadband inductorless low-noise amplifier (LNA) design that utilizes simultaneous noise
and distortion cancellation is presented. Concurrent cancellation of the intrinsic third-order …
