ABSTRACT A 86 MHz-12 GHz digital-intensive reconfigurable synthesizer is presented with 100 kHz to 2 MHz bandwidth. It leverages a 15 pJ/Shot 5.5 ps 14 b coarse-fine TDC and a 6-to-12 GHz dual-VCO set. The 0.28 mm2 synthesizer features simple background calibration, ¿¿ noise cancelation, and digital phase modulation, and consumes less than 30 mW.

    ABSTRACT: A mismatch-tolerant current-mode Sigma Delta (ΣΔ) Digital to Analog Converter (DAC) is presented here. The current mode DAC is designed such that the outputs of any two adjacent current elements can be progressively brought out for separate ΣΔ operation. This increases the DAC range even as the ΣΔ step size and range are kept small to minimize ΣΔ switching noise. Mismatch between DAC current elements can result in Differential Non Linearity (DNL) at the DAC output. A novel scheme is proposed to mitigate this effect. It involves skewing the thresholds of the quantizer in the ΣΔ modulator based on the DAC input, in order to control which DAC elements are used in generating a particular output current. The DAC, implemented as part of a Digital PLL in 90nm CMOS, yields a current range of up to 2mA and occupies an area of 0.035mm2. It is shown that the proposed scheme attenuates mismatch effects by a factor of 16.

    ABSTRACT: One emerging trend of implementing phase locked loop (PLL) based frequency synthesizers is to leverage digital signal processing in the loop filtering for more flexibility, scalability and smaller silicon area. This paper examines the pros and cons of such digital-intensive PLL architecture, and discusses techniques to minimize its overhead in terms of implementation cost and performance degradation. A hardware prototype in 65nm CMOS that synthesizes frequencies over 600-800 MHz is shown to prove the effectiveness the proposed overhead minimization techniques.

    ABSTRACT: State-of-the-art digital fractional-N PLLs intended for modern wireless systems make use of high-resolution and high-linearity time-to-digital converters (TDCs) in order to meet the stringent integral phase noise requirements. Those high-performance TDCs complicate the synthesizer design and dissipate large part of the power budget, leading to poor jitter-power compromise. This paper introduces a fractional-N PLL based on a 1b TDC, achieving jitter of 560fsrms (from 3kHz to 30MHz) at 4.5mW power consumption, even in the worst-case of fractional spur falling within the PLL bandwidth. The circuit synthesizes frequen cies between 2.92 and 4.05GHz with 70Hz resolution.
