摘要： Method and circuitry for controlling duty cycle of an input signal towards a desired value comprising a sequence of at least two inverters arranged in series and feedback circuitry. A first inverter is arranged to receive the input signal and a last inverter is arranged to output a signal having the same frequency as the input signal. The output signal is an adjusted version of the input signal. The feedback circuitry is arranged to receive the output signal and comprises a comparing and supplying means. The comparing means compares the output signal with a reference signal indicative of a desired value and generates a feedback signal based on the comparison of the output and reference signal. The supplying means supplies the feedback signal to adjust operating conditions of at least one of the inverters, such that the duty cycle of the output signal is controlled towards the desired value.

摘要： A transformer system includes a package substrate having a surface. A plurality of electrically conductive pads are arranged in spaced apart relationship relative to each other on the substrate surface. A first winding is defined by a first electrically conductive path between a first input and a first output, the first electrically conductive path including at least one wire connected between at least one first pad pair of the electrically conductive pads. At least one electrically conductive pad of each first pad pair is at the substrate surface. A second winding is defined by a second electrically conductive path between a second input and a second output, the second electrically conductive path including at least one wire connected between at least one second pad pair of the electrically conductive pads. At least one electrically conductive pad of each second pad pair is at the substrate surface. The first and second electrically conductive paths are proximal each other to achieve a magnetic field coupling between the first and second windings so as to form a transformer.

摘要： An apparatus and method for generating complementary periodic signals for a mixer circuit is provided. The apparatus comprises first and second generation circuits each for generating a periodic signal with a transition time on each rising edge different than a transition time on each falling edge. Each of the first and second generation circuits has an output for supplying its periodic signal to a mixer such that each rising edge of a periodic signal from one of the circuits crosses each falling edge of a periodic signal from the other of the circuits at a crossing point below a turn on voltage of the mixer.

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.
