TL;DR: The first all-digital PLL and polar transmitter for mobile phones is presented, exploiting the new paradigm of a deep-submicron CMOS process environment by leveraging on the fast switching times of MOS transistors, the fine lithography and the precise device matching, while avoiding problems related to the limited voltage headroom.

TL;DR: In this paper, the authors present a single-chip fully compliant Bluetooth radio fabricated in a digital 130-nm CMOS process, which is compatible with digital deep-submicron CMOS processes and can be readily integrated with a digital baseband and application processor.

TL;DR: This is the first known demonstration of an on-chip clock transmitter with an integrated antenna and the second demonstration of a clock receiver with anIntegrated antenna, where the receiver's frequency and interconnection distance have approximately been doubled over previous results.

TL;DR: The feasibility of integrating antennas and required circuits to form wireless interconnects in foundry digital CMOS technologies has been demonstrated and the key challenges including the effects of metal structures associated with integrated circuits, heat removal, packaging, and interaction between transmitted and received signals, and nearby circuits appear to be manageable.

TL;DR: In this paper, a digital controlled oscillator (DCO) architecture for multigigahertz wireless RF applications, such as short-range wireless connectivity or cellular phones, is proposed and demonstrated.
