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： A ratiometric clock system for an integrated receiver and associated method are disclosed that provide an advantageous solution for combining digital signal processing (DSP) circuitry on the same integrated circuit as mixer and local oscillator (LO) generation circuitry. The generation circuitry generates an oscillation signal that is passed through a first divider to generate mixing signals for the mixer and that is passed through a second divider to generate a digital clock signal that is utilized by the DSP circuitry. This digital clock signal can be utilized by integrated analog-to-digital conversion circuitry, as well.

摘要： A radio receiver such as a frequency modulation (FM) receiver, for example, includes a radio frequency (RF) amplifier having an adjustable gain output. The RF amplifier may be configured to receive and amplify an incoming RF signal. The receiver also includes an intermediate frequency (IF) amplifier having an adjustable gain output. The IF amplifier may be configured to receive and amplify an IF signal that corresponds to the RF signal. The receiver also includes a gain control unit that is coupled to the RF amplifier and the IF amplifier. The gain control unit may be configured to independently adjust the gain of each of the RF amplifier and the IF amplifier, dependent upon a peak output level of both the RF amplifier and the IF amplifier.

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.
