Ultra-Wideband, Low-Power, Inductorless, 3.1-4.8 GHz, CMOS VCO
A low-power, inductorless, UWB CMOS voltage controlled oscillator is designed in 0.18 μm CMOS technology targeting to a UWBFM transmitter application. The VCO is a Double-Cross-Coupled Multivibrator and generates output frequencies ranging from 1.55 GHz to 2.4 GHz. A low-power frequency doubler based on a Gilbert cell, which operates in weak inversion, doubles the VCO tuning range from 3.1 GHz ...

متن کاملA 5 GHz LC-VCO with Active Common Mode Feedback Circuit in Sub-micrometer CMOS Technology
A 1.2V 5GHz low-cost voltage-controlled oscillator (VCO) with active common mode feedback has been implemented in a CMOS/RF 90nm technology for a robust I/Q generation using a frequency divider-by-2 (DIV2). As the input common mode of the DIV2 affects critically its performance, a calibration method to correct the output common mode of the VCO has been proposed and validated through post-layout...

We demonstrated a 10GHz low phase noise differential Colpitts Voltage-Controlled Oscillator (VCO) utilizing TSMC 0.18 m μ 1P6M CMOS process with transformer coupling technology. The transformer coupling approach not only reduces the phase noise but also improves the power consumption owing to the number of active devices can be reduced. The total power consumption of this VCO is 20 mW and there...
متن کامل130 nm CMOS Mixer and VCO for 2.4 GHz Low-power Wireless Personal Area Networks
This paper describes a 2.4 GHz passive switch mixer and a 5/2.5 GHz voltage-controlled negative Gm oscillator (VCO) with an inversion-mode MOS varactor. Both circuits are implemented using a 1P8M 0.13 μm process. The switch mixer has an input referred 1 dB compression point of −3.89 dBm and a conversion gain of −0.96 dB when the local oscillator power is +2.5 dBm. The VCO consumes only 1.75 mW,...
