This paper focuses on the low VCO sensitivity gain design, and modeling of a low phase
noise 2.4 GHz PLL frequency synthesizer. Tuning switch array is used in the LC tank to …

Advances in CMOS technology permits realization of high speed and low noise integrated
frequency synthesizers and reduction in system costs. This project covers analysis, design …

A fully-differential quadrature PLL with common-mode noise immunity has been developed
by using a differentially controlled quadrature-VCO (Q-VCO) along with a differential charge …

Recently, frequency synthesizers are being designed in two ways narrow-band loop or dual-
loop for wide-band to reduce the phase noise. However, dual-loop has the disadvantage of …

A dual-loop frequency synthesizer is proposed to reduce the phase noise introduced by the
Voltage Controlled Oscillator (VCO) which is the main source of noise in a traditional PLL …

A phase-locked loop (PLL) frequency synthesizer with an on-chip passive discrete-time loop
filter is reported in this paper. The closed loop is robust stable, and a fast switching speed is …

In this paper, a 4.8 GHz fully integrated low power, low phase noise phase-locked loop
(PLL) frequency synthesizer ready for WLAN application is presented. It is implemented in a …

An LC-VCO based phase-locked loop (PLL) frequency synthesizer which incorporates loop
bandwidth tracking is described. In order to minimize loop bandwidth variations resulting …

A 5.1-GHz integer-N CMOS phase locked loop (PLL) based frequency synthesizer is
presented. A current mirror current source is used in designing the charge pump loop filter. A …

In this letter, a combined technique of self-injection locking and in-loop mixing (SIL-MIX) is
applied to a phase-locked loop (PLL) frequency synthesizer, which significantly reduces the …
