Low Phase Noise Voltage - Controlled Oscillator

A Low Power Low Phase Noise Lc Voltage- Controlled Oscillator

A low phase noise CMOS complementary cross-coupled LC-tank voltage-controlled oscillator (VCO), implemented with TSMC 0.18μm 1P6M CMOS technology, is presented. Double pair pseudoresistance transistors biased by the tapped center of the inductor are utilized to reduce the DC bias current. The circuit consumes 1.55 mA from a 1.5 V supply voltage which saves up to 52.4% power, compared with the c...

Voltage-Controlled Ring Oscillator for Low Phase Noise Application

A design for a voltage-controlled ring oscillator (VCO) is presented. The design allows an implementation of low frequency ring oscillator using relatively small devices and less stage. It is implemented using .18um technology provided by TSMC technology using 3.3V power supply. The VCO topology exhibits a very wide tuning range from few Hz to 368.9 MHz. It also features the rapid voltage swing...

Low-Power, Low-Phase-Noise CMOS Voltage-Controlled- Oscillator with Integrated LC Resonator

The recent rapid growth in demand for wireless communications has been a strong motivation for designing more highly integrated RF ICs like low-noise amplifiers (LNAs), upand down-frequency converters, voltagecontrolled oscillators (VCOs), and frequency synthesizers into a single die with low power consumption and cost, while meeting performance requirements for wireless communications systems....

A Low- Voltage Current-Controlled Oscillator

A new current-controlled oscillator (CCO) is presented which is suitable for use in low-voltage and lowpower designs. These features, and the low supply dependence of this CCO all stem from using a regenerative mechanism in its primitive delay cells. The circuit is designed and simulated in a 0.8um BiCMOS technology.
