    Abstract: A phase-frequency detector (110) is provided. The phase-frequency detector can include a frequency counter delay (147) for counting cycles of an output signal to generate a divided variable frequency delayed signal (FVd 146) having a time shift. A control stage (200) coupled to the output stage generates a pump up control signal (222) and a pump down control signal (234) in response to receiving the FVd signal, a divided variable frequency signal (FV 136), and a reference frequency signal (FR 106). The time shift provides an overlap region that allows both source (350) and sink (360) currents to be provided in phase lock. In phase lock, the duration of the pump up control signal approximates the duration of the pump down control signal within a linear region of operation.

    Abstract: Digital transmitters having improved characteristics are described. In one design of a digital transmitter, a first circuit block receives inphase and quadrature signals, performs conversion from Cartesian to polar coordinates, and generates magnitude and phase signals. A second circuit block (which may include a delta-sigma modulator or a digital filter) generates an envelope signal based on the magnitude signal. A third circuit block generates a phase modulated signal based on the phase signal. The third circuit block may include a phase modulating phase locked loop (PLL), a voltage controlled oscillator (VCO), a saturating buffer, and so on. A fourth circuit block (which may include one or more exclusive-OR gates or an amplifier with multiple gain states) generates a digitally modulated signal based on the envelope signal and the phase modulated signal. A fifth circuit block (which may include a class D amplifier and/or a power amplifier) amplifies the digitally modulated signal and generates an RF output signal.

    Abstract: A tracking circuit (100) is provided for controlling a locally-generated clock. A receive channel (110) in the tracking circuit receives an incoming signal and a local clock, generates a local signal based on the local clock, and compares the local signal and the incoming signal to generate a data signal and an unfiltered phase error signal. A loop filter (120) filters the unfiltered phase error signal to provide a filtered phase error signal. A numerically controlled oscillator (140) generates a correction clock based on the filtered phase error signal. And a filter control circuit (160) provides one or more filter control signals to control operational parameters of the loop filter. The correction clock is provided to the receive channel to modify at least one of the phase and frequency of the local clock. In addition, a sample switch (125) may also be provided to sample the unfiltered phase error signal.

    Abstract: Linear phase detectors comprising circuits (1,2) receiving reference signals (REF) and first and second clock signals (CLK-Q, CLK-I) for generating first and second (phase) control signals (UP,DOWN) for use in multiplier circuits, demodulators and receivers, have large delays due to long path lengths and many operations between input and output (insight). They can be made faster by providing each circuit (1,2) with two parallel latches (10,11,20,21) and a multiplexer (12,22) for multiplexing latch output signals (basic idea). Said multiplexers generate (frequency control) signals to be supplied to frequency detectors, with a third circuit (3) generating at least one of said (phase) control signals (UP,DOWN). Said third circuit (3) comprises a latch (30) generating said first (phase) control signal (UP), with one of the latches (20) of the second circuit (2) generating the second (phase) control signal (DOWN). Or said third circuit (3) comprises logical circuitry (31-34) comprising four EXOR gates (31-34). A fifth EXOR gate (35) is used for balancing the third circuit (3).
