A wideband digital frequency synthesizer

I I I I / With the rapid advance in CMOS technology. the trend.of the VLSI then towards system-on-chip (SOC) where design methodology. cost. and turnaround time are major issues. Concepts of intellectual property (IP) are then proposed to fit for SOC designs. Based on a DFS controller IP [4]. a wideband digital frequency synthesizer (DFS) is proposed to fit in with the wireless LAN applications...

TP 12.5: A 1.4GHz Differential Low-Noise CMOS Frequency Synthesizer using a Wideband PLL Architecture

The growing importance of wireless media for voice and data communications is driving a need for higher integration in personal communications transceivers in order to achieve lower cost, smaller form factor, and lower power dissipation [1]. One approach to this problem is to integrate the RF functionality in low-cost CMOS technology together with the baseband transceiver functions. This in tur...

A 1.35 GHz CMOS wideband frequency synthesizer for mobile communications

The design and simulation of a 1.35 GHz fully integrated CMOS frequency synthesizer for a double band receiver is presented. The proposed synthesizer is based in a wide-band PLL topology with a high reference frequency. This approach allows obtaining low phase noise, fast switching time, a low divider ratio and a reduction in the total chip area. Besides, the use of a novel charge-pump circuit ...

A New Ultra-Wideband Low Noise Amplifier With Continuous Gain Control

This paper presents a new variable gain low noise amplifier (VG-LNA) for ultra-wideband (UWB) applications. The proposed VG-LNA uses a common-source (CS) with a shunt-shunt active feedback as an input stage to realize input matching and partial noise cancelling. An output stage consists of a gain-boosted CS cascode and a gain control circuit that moves the high resonant frequency to higher freq...
