Abstract

A linear, low‐power, wideband 0.18‐μm CMOS VCO for UWB applications is presented, as part of a PLL‐based direct FM modulator for the 3.1–5‐GHz UWB band. It consists of a frequency control circuit and a differential ring core, coupled to the antenna output and the PLL prescaler by two single‐ended inverter buffers. The measured VCO exhibits a linear tuning range of 0.5–5.0 GHz, low power consumption of 2.5–10.5 mW, and an output power of −10 ± 1 dBm. © 2008 Wiley Periodicals, Inc.

## Abstract A low‐power GPS local generator using a 0.13‐μm CMOS process is presented. The complementary CMOS VCO, whose power consumption is about 0.6 mW, achieves the wide tuning range of 700 MHz and phase noise of −116 to −120 dBc/Hz at 1‐MHz frequency offset.

## Abstract In this article, a low‐power low‐phase‐noise 48‐GHz CMOS LC voltage‐control oscillator (VCO) using standard 0.13‐μm CMOS technology is reported. Low‐power consumption is achieved by maximizing the equivalent parallel resistance of the LC tank, while low‐phase‐noise is achieved by suppre
