چکیده

A low-power monolithic clock synthesizer suitable for use in mobile P platforms is presented. Clock synthesis is accomplished using an all-Si RF LC reference oscillator that does not require an external frequency reference. Fabricated in 0.18 m CMOS, the developed clock synthesizer demonstrates 1% frequency accuracy over process, voltage, and 0-70 C, exhibits 7.4/21/33psrms period jitter on 528/66/50MHz clock signals, and achieves a start-up latency of only 3.2 s.

A 12 GHz 1.9 W Direct Digital Synthesizer MMIC Implemented in 0.18 m SiGe BiCMOS Technology

This paper presents a 12 GHz direct digital synthesizer (DDS) MMIC with 9-bit phase and 8-bit amplitude resolution implemented in a 0.18 m SiGe BiCMOS technology. Composed of a 9-bit pipeline accumulator and an 8-bit sine-weighted current-steering DAC, the DDS is capable of synthesizing sinusoidal waveforms up to 5.93 GHz. The maximum clock frequency of the DDS MMIC is measured as 11.9 GHz at t...

A Low Jitter Vco and Frequency Divider for Frequency Synthesizer Applications

Timing information in the form of clock or oscillator signals play a critical role in most modern applications. The timing jitter or uncertainty in the timing information presents a serious limitation in the achievable system performance. For instance, timing errors can degrade the signal-to-noise ratio (SNR) of an A/D converter, limit the speed of a digital I/O interface or the bit error rate ...

Area efficient 0 . 18 um Cmos phase frequency detector for high speed Pll

Two phase frequency detectors (PFDs) are proposed in this paper that can overcome the speed and area limitations of conventional PFD. The AND gate based PFD uses 22 transistors. It consumes 161.41uW power when operating at 50MHz clock frequency with 1.8V supply voltage. The NOR gate based PFD uses 20 transistors and preserves the main characteristics of conventional PFD. It consumes 96.67uW pow...
