Patent application number | Description | Published |
20080204144 | Input stage for an amplifier - 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. | 08-28-2008 |
20080232480 | Receiver architectures for digital radio broadcasts and associated methods - 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. | 09-25-2008 |
