Latest Patents
Li Liu's latest patents include a wireless communications device that features a power detector circuit coupled to a sample signal at an interior node of an amplifier. This multi-stage amplifier consists of several amplifier stages in series, with a signal path extending through them. The power detector is strategically placed at an interior node along the signal path, allowing it to sample the first signal being transmitted. The output is a second signal that reflects the power of the first signal. In one embodiment, this interior node is part of a matching network situated between the first and final amplifier stages. The second signal can be utilized in a feedback network to adjust the amplification of the first signal by the amplifier.
Another patent focuses on accurate power detection for a multi-stage amplifier. Similar to the previous invention, this design includes a power detector coupled to an interior node of the amplifier. The power detector samples the first signal and outputs a second signal that indicates the power level of the first signal. This innovation aims to improve the feedback mechanisms that control amplification in multi-stage amplifiers.
