A 3.8-GHz highly linear <i>LC</i>-VCO without a varactor device

K-band Cmos Vco Using a Wide Tuning Range Varactor

This article presents a K-band CMOS voltage controlled oscillator (VCO) using a wide tuning range MOSFET varactor. The proposed varactor consists of a MOSFET in which the source and drain are connected to each other through a large resistor, the body is grounded through another large resistor, and the gate and source are connected through a capacitor. The newly proposed varactor improves the tu...

Design of a Highly Linear 24-GHz LNA

Conception of Low Phase Noise RF-VCO Using MOS Varactor

In this paper we propose new oscillator architecture (VCO2) and we compare it with a simple oscillator (VCO1). We describe the design and implementation of the differential LC-VCO for wireless applications. In this work we develop an analytical framework for determining the best VCO for a high-frequency synthesizer design based on the constraints of the application. We show methods for reducing...

18-GHz Clock Distribution Using a Coupled VCO Array

This paper describes an 18-GHz coupled VCO array for low jitter and low phase deviation clock distribution. To reduce the skew, jitter and power consumption associated with clock distribution, the clock is generated by a one-dimensional VCO array in which the oscillating nodes of adjacent VCOs are directly connected with wires. The effects of the wire length and number of unit VCOs in the array...

Chip-Package Co-Design of a 4.7 GHz VCO

Future wireless communication applications require low-power and highly integrated transceiver solutions. The integration of the RF front-end poses a great challenge, in particular, as traditional implementations require a large number of external passive components. “Single-package” integration of complete transceivers based on an MCM-D technology with integrated passives is presented in this ...
