Time-based circuits for communication systems in advanced CMOS technology
… the time domain. In this thesis, we focus on a ring oscillator as a core time-based circuit for communication systems. Ring oscillators are employed in analog-to-time conversion or time-to-digital conversion. In this work, we present A/D converters and an RF modulator based on ring oscillators …

Circuits for time-domain signal processing
… of bits (ENOB) of 13.4bits. Following that, a ring-VCO-based integer-N clock multiplier with feedforward noise cancellation is introduced to overcome the bandwidth limitation of conventional integer-N phase-locked loops (PLLs) by canceling the voltage controlled oscillator (VCO) noise in an …

A Robust Power-Scalable Transmitter Architecture for Wireless Body Area Networks
… modulo divider and a low-power NMOS delay-based ring-VCO acts as the oscillator. Several performance records are achieved: (1) The PA realizes a peak efficiency of 47% in the high-power (ISM) (-2 dBm) mode and 43% (33%) in the MedRadio -12 dBm (-16 dBm backoff) modes. (2) The PLL dissipates only …

Clock multiplication techniques for high-speed I/Os
… wireline systems. With the emphasis on ring oscillator based architecture using cascaded stages, three possible architectures are explored. First, a scrambling TDC (STDC) is presented to improve deterministic jitter (DJ) performance when used with a low-frequency reference clock. A …
