摘要： Aspects of a method and system for a mobile cellular television tuner utilizing current-steering variable gain at radio frequency are provided. A control signal may be generated in a LNA integrated within a single-chip multi-band RF receiver based on a gain signal. Adjusting a current flow through circuitry in an input stage within the LNA via the control signal may control a gain for the integrated LNA. A replica circuit within the LNA may be utilized to generate the control signal. A transconductor within the LNA may be utilized to convert the gain signal from a voltage to a current for generating the control signal. The gain signal may be generated on-chip or off-chip. A switched capacitor bank within the LNA may be adjusted to control the input scattering parameter. At least one bias voltage within the LNA may be adjusted during operation of the single-chip multi-band RF receiver.

摘要： Aspects of a method and system for a multi-band direct conversion CMOS mobile television tuner are provided. A single-chip multi-band RF receiver in a mobile terminal comprising UHF and L-band front-ends receives and amplifies an RF signal utilizing an LNA integrated into the front-end that corresponds to the type of signal received. A received signal strength indicator (RSSI) value may be determined for the amplified signal within the single-chip receiver and may be utilized to adjust a gain of the LNA. The adjustment may be made via on-chip or off-chip processing of the RSSI value. The single-chip receiver may directly convert the amplified signal to a baseband frequency signal and generate in-phase and quadrature components. The components of the baseband frequency signal may be filtered and/or amplified via programmable devices within the single-chip receiver. Circuitry within the single-chip receiver may be controller via an on-chip digital interface.
