  • Patent number: 9496840
    Abstract: A baseband signal-conditioning architecture applicable to radio receivers uses switched-capacitor techniques to provide high-performance signal conditioning in low-voltage, deep-submicron processes (e.g., 65 nm and below). In the architecture, a first mixer is coupled to an antenna receiving the signal, and outputs a first mixer output signal based on the signal received by the antenna. A buffer coupled to an output of the first mixer outputs a buffer signal based on the first mixer output signal. A first charge pump is coupled to an output of the buffer, and produces a first charge pump output signal based on the buffer signal. In some examples, a second charge pump is coupled to the output of the first mixer and produces a second charge pump output signal based on the first mixer output signal, and the buffer input is coupled to an output of the second charge pump.

  • Patent number: 9300307
    Abstract: A frequency synthesizer directly generates phase modulated radio-frequency (RF) signals. The frequency synthesizer includes a voltage controlled oscillator (VCO) producing a synthesized frequency signal having a frequency controlled based on a signal received at an input of the VCO. A digitally adjustable frequency divider produces a reduced frequency signal from the synthesized frequency signal. A phase digital-to-analog converter (DAC) produces a delayed version of a timing signal (e.g., the reduced frequency signal, or a reference clock signal) that is delayed according to a digital control signal. A phase detector (PD) produces a phase control signal from the reduced frequency signal and/or the delayed timing signal. A digital signal converter controls the digitally adjustable frequency divider and the phase DAC so as to cause a phase or frequency of the synthesized frequency signal output by the VCO to track a desired phase or frequency trajectory encoded in a digital signal.

  • Patent number: 8981833
    Abstract: Low-power circuits for providing stable voltage and current references rely on currents flowing through ultra-thin dielectric layer components for operation. A current reference circuit includes driving circuitry operative to apply a voltage to the first terminal of the component with respect to the second terminal of the component in order to cause a current to flow through the dielectric layer, and sources a reference output current that is based on the current flow through the dielectric layer in response to the applied voltage. A voltage reference circuit includes a current source which applies a current to the ultra-thin dielectric layer component, and maintains an output node at a stable reference output voltage level based on the voltage across the ultra-thin dielectric layer component in response to the current flow through the dielectric layer.

  • Patent number: 8558728
    Abstract: Phase noise in a first clock signal is measured using a time to digital converter (TDC) by determining variations in the phase delay between the first clock signal and a second clock signal. The TDC can include first and second series interconnections of delay elements, first and second sets of latches, and processing circuitry coupled to the latches and configured to determine the phase delay. The TDC can include a series interconnection of delay elements, latches, and circuitry configured to selectively adjust the control signal connected to the delay elements based on the output of the latches. The phase noise measurement can be used in a sampling circuit, so as to produce a second data signal from a first data signal based on the first clock signal and the measured phase noise.
