摘要： In one example, a semiconductor die includes multi-standard, multi-channel expandable television/satellite receiver that can be flexibly implemented in a number of different configurations to enable incorporation into a plurality of different systems. The semiconductor die may include multiple tuners to receive and tune a terrestrial radio frequency (RF) signal and a satellite RF signal. These tuners may include different frequency synthesizers including voltage controlled oscillators (VCOs) to generate VCO signals at different frequencies, mixers to downconvert the RF signals to baseband signals using the VCO signals. In an implementation, the semiconductor die may further include shared circuitry coupled to the tuners to digitize, process and demodulate the baseband signals.

摘要： A low-noise amplifier includes first and second transconductance paths and first and second variable capacitive dividers. The first transconductance path has a first terminal for receiving a first input signal, a control terminal, and a second terminal for providing a first output signal. The second transconductance path has a first terminal for receiving a second input signal, a control terminal, and a second terminal for providing a second output signal. The first variable capacitive divider has a first terminal for receiving the first input signal, a second terminal coupled to a reference voltage terminal, and an intermediate terminal coupled to the control terminal of the second transconductance path. The second variable capacitive divider has a first terminal for receiving the second input signal, a second terminal coupled to the reference voltage terminal, and an intermediate terminal coupled to the control terminal of the first transconductance path.

摘要： Receiver architectures and associated methods are disclosed that provide initial analog coarse tuning of desired channels within a received signal spectrum, such as a set-top box signal spectrum for satellite communications. These architectures provide significant advantages over prior direct down-conversion (DDC) architectures and low intermediate-frequency (IF) architectures, particularly where two tuners are desired on the same integrated circuit. Rather than using a low-IF frequency or directly converting the desired channel frequency to DC, initial coarse tuning provided by analog coarse tuning circuitry allows for a conversion to a frequency range around DC. This coarse tuning circuitry can be implemented, for example, using a large-step local oscillator (LO) that provides a coarse tune analog mixing signal. Once mixed down, the desired channel may then be fine-tuned through digital processing, such as through the use of a wide-band analog-to-digital converter (ADC) or a narrow-band tunable bandpass ADC.

摘要翻译：公开了接收机架构和相关方法，其提供接收信号频谱内的期望信道的初始模拟粗调，例如用于卫星通信的机顶盒信号频谱。这些架构与先前的直接下变频（DDC）架构和低中频（IF）架构相比具有显着的优势，特别是在同一集成电路上需要两个调谐器的情况下。不是使用低IF频率或直接将期望的信道频率转换为DC，而是由模拟粗调谐电路提供的初始粗调调可以转换到大约DC的频率范围。该粗调谐电路可以例如使用提供粗调模拟混频信号的大步本地振荡器（LO）来实现。一旦混合，则可以通过数字处理（例如通过使用宽带模数转换器（ADC）或窄带可调谐带通ADC）来微调所需的信道。
