The impedance matching elements may include capacitors and inductors. Between each adjacent pair of the respective drivers coupled to each of the plurality of VCOs, the impedance matching elements may include two inductors coupled in series between the drivers and a capacitor coupled to ground and to a common node between the two inductors. Impedance values of the capacitors and inductors may be configurable. The impedance matching elements may include a resistor coupled to a bias voltage VDD and to a common node with a capacitor that is coupled to ground, where the common node is coupled to one of the inductors. The output device may include a prescaler that is an integer or fractional frequency-N divider, or a buffer. The respective drivers coupled to each of the plurality of VCOs may be configured to provide a constant output power no matter which of said plurality of VCOs is enabled.

Abstract: Methods and systems for a configurable low-noise amplifier with programmable band-selection filters may comprise a receiver with a low-noise amplifier (LNA) with first and second input terminals and differential output terminals; a low pass filter operably coupled to the LNA; a high pass filter operably coupled to the second input terminal of the LNA; and a signal source input coupled to the low pass filter and the high pass filter. The LNA may be operable to receive signals in a pass band of the high pass filter and a pass band of the low pass filter. The receiver may be operable to amplify input signals in the pass band of a first filter but not signals in the pass band of the second filter by operably coupling the second to ground.

Abstract: Aspects of methods and systems for high frequency signal selection are provided. The system for high frequency signal selection comprises a first driver and a second driver. The first driver is able to receive a first high frequency input, and the second driver is able to receive a second high frequency input. The output of the first driver is operably coupled, via a first inductive element, to a first resistive load and a first buffer, and the second driver is operably coupled, via a second inductive element, to the output of the first driver. One or both of the first high frequency input and the second high frequency input may be transferred to the first buffer by selectively enabling a current to one or both of the first driver and the second driver, respectively.

Abstract: Methods and systems for a configurable low-noise amplifier with programmable band-selection filters may comprise a low-noise amplifier (LNA) with a low pass filter coupled to a first input of the LNA and a high pass filter coupled to a second input of the LNA. The low pass filter and the high pass filter may also be coupled to a signal source input. Signals may be received in a pass band of the high pass filter and a pass band of the low pass filter. Input signals in the pass band of the one filter (but not signals in the pass band of the other filter) may be amplified by coupling the one input of the LNA to ground and coupling the other filter to ground utilizing a shunt resistor. The filters may be configurable and may each comprise at least one inductor and at least one capacitor.
