An optimized 2.4GHz VCO circuit design and simulation with high-Q MEMS LC-tank

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...

Low-phase-noise Cmos Vco with Harmonically Tuned Lc Tank

A low-phase-noise voltage-controlled oscillator (VCO) has been demonstrated using a harmonically tuned LC resonance tank. In this circuit configuration, the voltage shape at the differential cell is almost rectangular; thus, the cell is switched effectively and the phase noise is reduced. More importantly, the proposed tank suppresses downconversion of the noise around 2f0 to the phase noise, d...

24GHz CMOS direct downconversion receiver front-end and VCO design

The explosive growth of today's wireless communication market has brought an in­ creasing demand for high performance radio-frequency (RF) circuits in low-cost tech­ nologies. Because of advancements in RF CMOS circuits, devices, and passive elements in the last decade, it has become possible to develop a RF system-on-chip (SoC) that integrates RF, analog and digital circuits completely. Direct...

simulation and design of electronic processing circuit for restaurants e-procurement system

the poor orientation of the restaurants toward the information technology has yet many unsolved issues in regards to the customers. one of these problems which lead the appeal list of later, and have a negative impact on the prestige of the restaurant is the case when the later does not respond on time to the customers’ needs, and which causes their dissatisfaction. this issue is really sensiti...
