摘要： A wideband frequency generator has two or more oscillators for different frequency bands, disposed on the same die within a flip chip package. Coupling between inductors of the two oscillators is reduced by placing one inductor on the die and the other inductor on the package, separating the inductors by a solder bump diameter. The loosely coupled inductors allow manipulation of the LC tank circuit of one of the oscillators to increase the bandwidth of the other oscillator, and vice versa. Preventing undesirable mode of oscillation in one of the oscillators may be achieved by loading the LC tank circuit of the other oscillator with a large capacitance, such as the entire capacitance of the coarse tuning bank of the other oscillator. Preventing the undesirable mode may also be achieved by decreasing the quality factor of the other oscillator's LC tank and thereby increasing the losses in the tank circuit.

摘要： A sub-harmonic mixer includes a first transistor having a source and a drain and a second transistor having a source connected to the source of the first transistor and a drain connected to the drain of the first transistor. A mixing transistor is configured to be biased in a linear operating region. The mixing transistor includes a drain coupled to the sources of the first transistor and the second transistor.

摘要： A capacitance switching element includes first and second capacitors connected in series by transistors. The gates of the transistors are biased by a first signal through one set of resistors, and the sources and drains are biased by a second signal through a second set of resistors. The signals are level-shifted and may be complimentary. To turn the element ON, the first signal may be set to VDD and the second signal may be set to zero. To turn the element OFF, the first signal may be set to a multiple of VDD/2 and the second signal may be set to the multiple plus one of VDD/2. When the element is used in an oscillator tuning circuit, the voltage stress on the transistors is reduced and the transistors may be fabricated with thin oxide. The oscillator may be used in a transceiver of a cellular access terminal.

摘要： An RF buffer circuit for a voltage controlled oscillator (VCO) includes dynamic biasing circuitry to selectively flip the phase of the output voltage waveform. In a CMOS implementation, a PMOS/NMOS pair is employed in an output path. During a high (voltage) swing mode condition, the phase of the output is flipped such that the output waveform is in phase with the voltages appearing at the gates of the PMOS/NMOS pair. The technique thereby reduces peak gate-to-drain voltages and allows for improved reliability of the MOS devices in a configuration amenable to low phase noise and low power consumption.

摘要： A method includes setting a mode of operation of a buffer circuit outputting an output signal. The mode of operation is set to a first mode of operation or a second mode of operation. The output signal is substantially in-phase with an input signal received by the buffer circuit when the mode of operation is the first mode. The output signal is substantially out of phase with the input signal when the mode of operation is the second mode.
