摘要： A phase-frequency detector generates output signals at a first and a second output end based on input signals received at a first and a second input end. The phase-frequency detector includes two latch circuits, two pulse generators, two inverting circuits, two sensing devices, and a reset control circuit. The sensing devices control the pulse generators based on signals received at corresponding first ends of the sensing devices. The inverting circuits generate signals to the first and second output ends of the phase-frequency detector based on signals received at corresponding first ends of the inverting circuits. The reset control circuit generates reset signals based on signals received at the first and second output ends of the phase-frequency detector.

摘要： A mobile system has a frequency synthesizer and an amplifier module coupled to the frequency synthesizer. The frequency synthesizer is controlled by frequency division data to generate a tuning signal with a frequency corresponding to a reference signal and the frequency division data. The mobile system provides an input signal based on the frequency of the tuning signal having a frequency spectrum corresponding to the frequency of the tuning signal. The amplifier module has a variable load circuit for providing an equivalent impedance, an amplifier circuit coupled to the variable load circuit for establishing an output signal corresponding to the input signal and the equivalent impedance of the variable load circuit, and a mapping circuit for modifying the equivalent impedance of the variable load circuit based on the frequency division data.
