Abstract: A frequency multiplier includes a capacitor circuit having a plurality of capacitors therein, and is responsive to a differential input signal applied to an inverting input node and a non-inverting input node thereof. A frequency multiplication circuit (FMC) is provided, which has a plurality of transistors therein. The FMC is configured to receive components of the differential input signal passing through the plurality of capacitors, and multiply a frequency of the components of the differential input signal. A plurality of inductor loads are provided, which are connected to an inverting output node and a non-inverting output node of the FMC, and are configured to convert a current signal generated by the FMC into a voltage signal.

Abstract: Provided is an electronic device that includes a first processor for receiving an audio signal, performing first voice recognition on the audio signal, and transferring a driving signal to a second processor based on a result of the first voice recognition. The second processor performs second voice recognition based on a voice signal by the first voice recognition or the audio signal, in response to the driving signal.
