Design and Simulation of an X Band LC VCO
In this paper, a systematic method for the circuit parameters design of a monolithic LC Voltage Controlled Oscillator (VCO) is reported. The method is based on the negative resistance generation technique. As a result, a VCO has been designed in 0.18um CMOS technology using a conventional VCO structure to obtain the optimum values for the phase noise and power consumption. The simulation result...
متن کاملA LOW-POWER DOUBLE BALANCED OSCILLATOR MIXER DESIGN IN 90nm CMOS TECHNOLOGY
CMOS Scaling technologies are the main caused for great impact on Analog design. The most severe affect is the reduction in the voltage supply. A double balanced down conversion oscillator mixer using 90 nm CMOS technology is proposed in this work. This oscillator mixer consists of an individual mixer stacked on a voltage-controlled oscillator (VCO). The proposed stacked structure allows entire...
متن کاملA 2.4 GHz 3.6mW 0.35mm2 Quadrature Front-End RX for ZigBee and WPAN Applications
a cheaper design. Since an LC-oscillator topology is mandatory to achieve a minimal current draw, the reduction of the number of coils has to be done in the LNA, the mixer and the quadrature generator. In this work, starting from the LNA-Mixer and VCO (LMV) cell topology [2], a single-coil low-power receiver shares the bias current among all the RF blocks of the analog front-end. The receiver p...
متن کاملDesign and Implementation of A 6-GHz Array of Four Differential VCOs Coupled Through a Resistive Network
This paper presents the design and the implementation of a fully monolithic coupledoscillator array, operating at 6 GHz with close to zero coupling phase, in 0.25 μm BICMOS SiGe process. This array is made of four LC-NMOS differential VCOs coupled through a resistor. The single LC-NMOS VCO structure is designed and optimized in terms of phase noise with a graphical optimization approach while s...
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,...
