摘要： A long-wave or medium-wave receiver receives a first signal from a first terminal of a loopstick antenna on a positive antenna input terminal of the receiver and receives a second signal from a second terminal of the loopstick antenna on a negative antenna input terminal of the receiver. The first and second signals are processed differentially in the receiver. The receiver may optionally be configured to operate in either a differential mode or a single-ended mode by setting switches to selectively connect one of the antenna input terminals to ground in single-ended mode.

摘要： In one embodiment, the present invention includes a single chip radio tuner, which may be adapted within an integrated circuit (IC). The tuner may be provided with a configurable front end to receive and process a radio frequency (RF) signal via a signal path. This configurable front end may be differently controlled depending on a particular radio implementation in which the tuner is adapted.

摘要： A system and method are disclosed for using dynamic supply voltages to bias circuit blocks within integrated circuits. By considering current requirements for circuit blocks based upon process variations and environmental conditions, a dynamic supply voltage can be used such that operational integrity can be maintained while reducing power consumption. By using a dynamic supply voltage, circuit blocks can be operated at a desired speed while still reducing the power required for this operation. To implement this dynamic supply regulation, circuit elements are provided within a variable supply voltage circuit that cause the dynamic supply voltage to vary based upon operational parameters such as process variations and environment parameters. As such, circuit blocks can be provided a supply voltage high enough to allow operational integrity at required speeds but not so high as to waste power by unnecessarily increasing current consumption.
摘要翻译：公开了一种使用动态电源电压来偏置集成电路内的电路块的系统和方法。通过考虑基于工艺变化和环境条件的电路块的当前要求，可以使用动态电源电压，从而可以在降低功耗的同时保持操作完整性。通过使用动态电源电压，可以以期望的速度操作电路块，同时仍然减少该操作所需的功率。为了实现这种动态电源调节，电路元件被提供在可变电源电压电路内，使得动态电源电压基于诸如工艺变化和环境参数的操作参数而变化。因此，电路块可以被提供足够高的电源电压以允许在所需速度下的操作完整性，但不高于通过不必要地增加电流消耗来浪费功率。

摘要： A wireless communication receiver is disclosed that operates in a test mode to determine image correction information that is used to suppress undesired image signals when the receiver switches to a normal operational mode. In one embodiment, the receiver includes a frequency synthesizer coupled by a quadrature divider to an in-phase (I) mixer and a quadrature mixer. The mixers are coupled by respective analog to digital converters (ADCs) to respective I and Q channel inputs of a digital signal processor (DSP). In the test mode, a test tone is provided to the mixer inputs. The test tone is divided down further and provided to clock the frequency synthesizer, the ADCs and the DSP. This configuration locks together the mixers, frequency synthesizer, ADCs and DSP ratiometrically in frequency during the test mode while image correction information is being determined. When the receiver switches to a normal operating mode, the frequency synthesizer, ADCs and DSP are clocked by a main clock signal instead of the divided down test tone, and the test tone is removed from the mixers.

Each of the varactor cells includes a switch that includes a first terninal to receive the control signal and a second terminal such that the switch operates to control a capacitance of the varactor cell in response to a voltage between the first and second terminals. The oscillator includes a bias circuit to provide a different bias voltage to each second terminal and an amplifier that is coupled to the varactor cells to generate an oscillating signal.
