  • Publication number: 20150372665
    Abstract: A quadrature LC tank based digitally controlled ring oscillator (DCO). The oscillator structure incorporates a plurality of stages, each stage including a buffer and a series LC tank. Four stages are coupled together to create a 360 degree phase shift around a loop. The oscillation frequency of the oscillator is the same as the resonant frequency of each LC tank, therefore it avoids quality factor degradation of LC tanks found in the prior art. In one example embodiment, class-D amplifiers are used to drive each of the LC tanks Capacitor banks before at the input and output of the buffers provide coarse and fine tuning of the frequency of oscillation. The high efficiency exhibited by these amplifiers results in very good phase noise performance of this oscillator. The oscillator utilizes a startup circuit to launch oscillation upon power on.

  • Patent number: 9197221
    Abstract: A novel and useful oscillator topology demonstrating an improved phase noise performance that exploits the time-variant phase noise model with insights into the phase noise conversion mechanisms. The oscillator is based on enforcing a pseudo-square voltage waveform around an LC tank by increasing the third-harmonic of the fundamental oscillation voltage through an additional impedance peak. Alternatively, the oscillator is based on enforcing clipped oscillation waveform by increasing the second harmonic of the fundamental oscillation voltage through an additional impedance peak. This auxiliary impedance peak is realized by a transformer with moderately coupled resonating windings. As a result, the effective impulse sensitivity function (ISF) decreases thus reducing the oscillator's effective noise factor such that a significant improvement in the oscillator phase noise and power efficiency are achieved.

  • Patent number: 9148125
    Abstract: A novel and useful high-order discrete-time charge rotating (CR) infinite impulse response (IIR) low-pass filter is presented. The filter utilizes capacitors and a gm-cell, rather than operational amplifiers, and is thus compatible with digital nanoscale technology. A 7th-order charge-sampling and 6th-order voltage-sampling discrete time filter is disclosed. The order of the filter is easily extendable to higher orders. The charge rotating filter is process-scalable with Moore's law and amenable to digital nanoscale CMOS technology. Bandwidth of this filter is precise and robust to PVT variation. The filter exhibits very low power consumption per filter pole, low input-referred noise, wide tuning range, excellent linearity and low area per minimum bandwidth and filter pole.

  • Patent number: 9118335
    Abstract: A novel and useful millimeter-wave digitally controlled oscillator (DCO) that achieve a tuning range greater than 10% and fine frequency resolution less than 1 MHz. Switched metal capacitors are distributed across a passive resonator for tuning the oscillation frequency. To obtain sub-MHz frequency resolution, tuning step attenuation techniques are used that exploit an inductor and a transformer. A 60-GHz fine-resolution inductor-based DCO (L-DCO) and a 60 GHz transformer-coupled DCO (T-DCO), both fabricated in 90 nm CMOS, are disclosed. The phase noise of both DCOs is lower than ?90.5 dBc/Hz at 1 MHz offset across 56 to 62 GHz frequency range. The T-DCO achieves a fine frequency tuning step of 2.5 MHz, whereas the L-DCO tuning step is over one order of magnitude finer at 160 kHz.
