摘要： Radio-frequency (RF) apparatus includes receiver analog circuitry that receives an RF signal and provides at least one digital signal to receiver digital circuitry that functions in cooperation with the receiver analog circuitry. The receiver analog circuitry and the receiver digital circuitry are partitioned so that interference effects between the receiver analog circuitry and the receiver digital circuitry tend to be reduced.

摘要： A circuit is provided for use with analog to digital conversion techniques in sampled amplitude read channel integrated circuits. A common ADC may be utilized for conversion of both high frequency disk data such as user data and servo data, for example, and for low frequency auxiliary data such as, for example, motor back-EMF current signals. The ADC may utilize the relatively low bit accuracy required for the read channel disk data and through oversampling techniques obtain sufficient conversion accuracy to meet the relatively higher precision requirements for the auxiliary data conversion. The auxiliary data is modified by a ramp signal and the ADC is run on a clock generated from a dithered frequency source so that ADC quantization errors may be randomized.
摘要翻译：在采样幅度读通道集成电路中提供用于模数转换技术的电路。例如，可以使用公共ADC来转换诸如用户数据和伺服数据的高频盘数据，以及用于低频辅助数据，例如电动机反电动势电流信号。 ADC可以利用读通道盘数据所需的相对较低的位精度，并且通过过采样技术获得足够的转换精度以满足对辅助数据转换的相对较高的精度要求。辅助数据由斜坡信号修改，ADC在从抖动频率源产生的时钟上运行，因此ADC量化误差可以随机化。

摘要： Receiver architectures and related methods are disclosed for high definition (HD) and digital radio FM broadcast receivers. The radio receiver architectures are configured to utilize multiple analog-to-digital converters (ADCs) to handle the digital radio spectrum and can be configured to modify a target IF frequencies depending upon the mode of operation of the receiver. For example, the receiver can include an analog FM reception mode and a digital FM reception mode for which different down-conversions are used for the same analog-plus-digital audio broadcast channel. If desired, the radio broadcast receivers disclosed can be configured so that they only receive digital FM radio content, for example, if the analog FM broadcast was of no interest and/or if the broadcast was all digital.

摘要： In one embodiment, the present invention includes an amplifier having an input to receive a radio frequency (RF) signal from an output node of a source. An input stage coupled to the amplifier input may include one or more components to aid in processing of incoming signals. One such component coupled between the source and the input of the amplifier is a coupling capacitor used to maintain a bias voltage of the amplifier at a different potential than a DC voltage of the output node. In certain applications, the amplifier and the coupling capacitor may be integrated on a single substrate.

摘要： A radio-frequency (RF) receiver includes a receiver analog circuitry and a receiver digital circuitry. The receiver analog circuitry resides within a first integrated circuit and the receiver digital circuitry resides within a second integrated circuit. The second integrated circuit couples to the first integrated circuit via a one-bit digital interface. The receiver analog circuitry receives an RF signal and processes the received RF signal to generate a digital signal. The receiver analog circuitry provides the digital signal to the receiver digital circuitry. The receiver digital circuitry includes a digital down-converter circuitry that mixes the digital signal with an intermediate frequency (IF) local oscillator (LO) signal to generate a digital down-converted signal. The receiver digital circuitry also includes a digital filter circuitry that filters the digital down-converted signal to generate a filtered digital signal.
