摘要： An amplifier circuit includes a power amplifier biased for saturated mode operation, and a controllable current source to provide supply current to the power amplifier. The controllable current source effects desired amplitude modulation of the output signal from the power amplifier by modulating the supply current it provides responsive to an amplitude information signal. In one or more embodiments, the current source includes a circuit that is configured to adjust one or more transmitter operating parameters responsive to detecting changes in the effective DC resistance of the power amplifier. For example, the circuit may generate a compensation signal that reduces the effective DC resistance responsive to detecting that the effective DC resistance has undesirably increased. By way of non-limiting examples, such compensation may be effected by changing a current mirror, an amplifier-to-antenna impedance matching, an amplifier bias or device size, or imposing some form of transmit signal back-off.

摘要： Techniques for generating bias voltages for a multi-cascode amplifier. In an aspect, a multi-cascode bias network is provided, each transistor in the bias network being a replica of a corresponding transistor in the multi-cascode amplifier, enabling accurate biasing of the transistors in the multi-cascode amplifier. In another aspect, a voltage supply for the multi-cascode amplifier is provided separately from a voltage supply for the replica bias network, to advantageously decouple variations in the amplifier voltage supply from the bias network voltage supply. In yet another aspect, the bias voltages of transistors in the multi-cascode amplifier may be configured by adjusting the impedance of resistive voltage dividers coupled to the transistor gate biases. As the gain of the amplifier depends on the bias voltages of the cascode amplifiers, the gain of the amplifier may be adjusted in this manner without introducing a variable gain element directly in the amplifier signal path.
摘要翻译：用于产生多共源共栅放大器偏置电压的技术。在一方面，提供了一种多共源共栅偏压网络，偏置网络中的每个晶体管是多共源共栅放大器中对应的晶体管的复制品，使多级共源共栅放大器中的晶体管能够精确偏置。在另一方面，用于多重共源共栅放大器的电压源与用于复制偏压网络的电压源分开提供，以有利地将放大器电压源与偏置网络电压源的变化分离。在另一方面，多并联放大器中的晶体管的偏置电压可以通过调整耦合到晶体管栅极偏置的电阻分压器的阻抗来配置。由于放大器的增益取决于共源共栅放大器的偏置电压，所以可以以这种方式调节放大器的增益，而不将可变增益元件直接引入放大器信号路径。
