摘要： Techniques for decimating a first periodic signal to generate a second periodic signal. In an exemplary embodiment, the first periodic signal is divided by a configurable integer ratio divider, and the output of the divider is delayed by a configurable fractional delay. The configurable fractional delay may be noise-shaped using, e.g., sigma-delta modulation techniques to spread the quantization noise of the fractional delay over a wide bandwidth. In an exemplary embodiment, the first and second periodic signals may be used to generate the transmit (TX) and receive (RX) local oscillator (LO) signals for a communications transceiver from a single phase-locked loop (PLL) output.

摘要： A feedforward nonlinearity cancellation scheme is used to improve the linearity of a low noise amplifier (LNA). An LNA incorporates a main amplifier and an auxiliary amplifier couple to receive the same input. The outputs of the main amplifier and the auxiliary amplifier are also coupled. The auxiliary amplifier may be implemented as a very low power auxiliary amplifier having a very low linearity. The output of the auxiliary amplifier contains third-order intermodulation (IM3) products that are of similar amplitude, but opposite phase, to the IM3 products generated by the main amplifier. With the outputs of the main amplifier and the auxiliary amplifier coupled, their respective IM3 products are summed together and effectively cancel each other out. As a result, the output of the LNA contains substantially no IM3 products, and the linearity of the LNA is substantially improved.

摘要： In one aspect, a digital PLL (DPLL) operates based on fractional portions of input and output phases. The DPLL accumulates at least one input signal to obtain an input phase. The DPLL determines a fractional portion of an output phase based on a phase difference between an oscillator signal from an oscillator and a reference signal, e.g., using a time-to-digital converter (TDC). The DPLL determines a phase error based on the fractional portion of the input phase and the fractional portion of the output phase. The DPLL then generates a control signal for the oscillator based on the phase error. In another aspect, a DPLL includes a synthesized accumulator that determines a coarse output phase by keeping tracking of the number of oscillator signal cycles based on the reference signal.

摘要： A local oscillator includes a phase-locked loop. The phase-locked loop includes voltage controlled oscillator (VCO) and a novel VCO control circuit. The VCO control circuit may be programmable and configurable. In one example, an instruction is received onto the VCO control circuit to change the power state of the VCO. The instruction is issued by other circuitry in response to a detected change in RF channel conditions (for example, a change in a signal-to-noise determination) in a cellular telephone. In response, the VCO control circuit outputs control signals that gradually widen the loop bandwidth of the PLL, then gradually change the VCO bias current to change the VCO power state, and then narrow the loop bandwidth of the PLL back to its original bandwidth. The entire process of widening the PLL bandwidth, changing the VCO power state, and narrowing the PLL bandwidth occurs while the PLL remains locked.
