摘要: A device is provided for dividing a clock signal by even and odd integers. The device includes a divider, a delay portion and a duty cycle corrector. The divider is arranged to receive the clock signal and can divide the clock signal and output a divided clock signal. The delay portion can output a delayed signal based on the divided clock signal. The duty cycle corrector can output a first signal based on the delayed signal and the divided clock signal.

摘要: A frequency modulation (FM) receiver with a low power frequency synthesizer. A FM receiver includes a low noise amplifier for processing a received input signal, a frequency synthesizer having an oscillator for generating a local oscillator signal by supplying a bias current to the oscillator, and a mixer for generating an intermediate frequency signal by mixing the received input signal with the local oscillator signal. The FM receiver further includes an analog to digital converter for converting the intermediate frequency signal to a digital signal and a bias current control module for measuring a signal strength of the received input signal based on the digital signal and for controlling the bias current.

摘要: Frequency synthesizer with immunity from oscillator pulling. The frequency synthesizer for generating an output frequency includes an oscillator that is capable of generating a first frequency. The frequency synthesizer also includes an output divider coupled to the oscillator. The output divider is configurable to allow the oscillator to generate a second frequency to prevent degradation in phase noise due to an interference to the first frequency of the oscillator, and to generate the output frequency from the second frequency.
