A low power low phase noise dual-band multiphase VCO
This paper presents a low-power low-phase noise multiphase VCO that operates in 2.5 GHz and 5.0 GHz frequency bands. The dual-band multiphase VCO uses the frequency doubling method to generate the higher band signals from ...
MOSFET drain current noise modeling with effective gate overdrive and junction noise
In this letter, a drain current noise model that includes the channel thermal noise and the shot noise generated at the source-bulk junction and the drain-bulk junction is presented. A unified analytical expression is ...
Impact of velocity saturation and hot carrier effects on channel thermal noise model of deep sub-micron MOSFETs
This paper discusses the impact of the short channel effects, such as channel length modulation (CLM), velocity saturation effect (VSE) and hot carrier effect (HCE), on the channel thermal noise model of short channel ...
A 1.2 V 2.4 GHz low spur CMOS PLL synthesizer with a gain boosted charge pump for a batteryless transceiver
This paper presents a low power 1.2 V, 2.4 GHz low spur, Quadrature PLL synthesizer for IEEE 802.15.4 batteryless transceiver in CMOS 0.18 μm technology. The PLL employs a 1 MHz fully programmable divider with an improved ...
Design of quarter-wavelength resonator filters with coupling controllable paths
This paper presents compact quarter-wavelength resonator filters to have multiple transmission zeros points (ZPs) with controllable electric and magnetic coupling paths. For two coupled resonators, the relative strength ...
A low-power single-phase clock multiband flexible divider
In this paper, a low-power single-phase clock multiband flexible divider for Bluetooth, Zigbee, and IEEE 802.15.4 and 802.11 a/b/g WLAN frequency synthesizers is proposed based on pulse-swallow topology and is implemented ...
