摘要： A method of estimating mismatches of a time-to-digital converter (TDC) includes: capturing phase error samples; calculating difference between the phase error samples and an expected value of the phase error samples; and adjusting correction gain of the TDC based on the calculating step. Another method of estimating mismatches of a TDC includes: capturing TDC output code samples; storing a plurality of accumulation values corresponding to different TDC values respectively, wherein each accumulation value records a number of times a TDC value is carried by the TDC output code samples; calculating a desired value based on the accumulation values; calculating difference between the accumulation values and the desired value; and adjusting correction gain of the TDC based on the calculating step.

摘要： A transmitter is provided. The transmitter includes a phase/frequency deviation input, a controller and a frequency modulating path. The phase/frequency deviation input receives multiple phase/frequency deviation samples. The controller outputs a modified phase/frequency deviation signal and generates a phase/frequency deviation carry-out signal in response to the phase/frequency deviation samples and a previous time sample of the phase/frequency deviation carry-out signal. The frequency modulating path performs frequency modulation in response to the modified phase/frequency deviation signal and outputs a frequency modulated carrier signal.

摘要： An embodiment of the present invention provides a phase locked loop that operates on clock signals derived from an RF clock signal generated by the phase locked loop. A frequency reference input provides a reference clock. A controllable oscillator generates the RF clock signal. A phase detection circuit operates on the reference clock to provide digital phase error samples indicative of a phase difference between the reference clock and the RF clock. A dithering circuit is coupled to the reference signal and injects a short sequence dither signal into the reference signal in order to overcome quantization noise and thereby improve RMS phase-error detection for integer channels.

摘要： Methods to implement low cost, high efficiency, low loss power combiner with novel matching circuits are disclosed. A narrow band power combiner enables a high power and high efficiency radio frequency power amplifier to be realized using multiple low voltage CMOS transistors or micro power amplifiers. The power combiner may be printed on a package substrate and realized either using single layer substrate through edge coupling or multiple layers substrate through broadside coupling. The micro power amplifiers may be fabricated using low voltage CMOS technology and electrical connections between the outputs from the micro power amplifiers and the power combiner may be provided through stud bumps in a flip chip technology. With the tunable matching circuits, the present invention allows the narrow band power combiner to be tuned to different frequencies.

摘要： A novel and useful RF oscillator suitable for use in applications requiring ultra-low voltage and power. The oscillator structure, employing alternating current source transistors, combines the benefits of low supply voltage operation of conventional NMOS cross-coupled oscillators together with high current efficiency of the complementary push-pull oscillators. In addition, the 1/f noise upconversion is also reduced. The oscillator can be incorporated within a wide range of circuit applications, including for example a conventional phase locked loop (PLL), all-digital phase-locked loop (ADPLL), wireline transceiver circuits and mobile devices.
