摘要:
An electronic power converter (204) is configured to receive power from a power source (202). The power operates at a switching frequency. The electronic power converter includes a resonant tank circuit (206) operatively connected to the power converter. The resonant tank circuit operates at a tank resonant frequency. The electronic power converter includes a controller (208) operatively connected to the resonant tank circuit. The electronic power converter further includes a variable inductor (300) operatively connected to the resonant tank circuit. The variable inductor is configured to modify the tank resonant frequency to match the switching frequency within a predetermined margin.

The present disclosure relates to a front-end system for a radio device comprising a converter, the converter comprising a mixer configured for down-converting a radio frequency signal into a baseband signal by using a local oscillator signal generated by a signal generator, and characterized in that, said converter further comprises a quantizer arranged for quantizing said baseband signal into a digital signal, and wherein the signal generator is configured for generating, based on said digital signal, said local oscillator signal such that it is synchronized with the radio frequency signal.
摘要:
A programmable variable admittance circuit may be used In a programmable filter or a variable gain amplifier in a number of different applications including tuners and other RF receiver circuits. A variable admittance circuit and operation is described including a number of switchable admittance elements arranged In parallel branches, The variable admittance circuit requires fewer transitions to change between successive admittance values than a binary weighted circuit and fewer branches for implementation then a thermometric admittance circuit.
