Latest Patents
One of Yu Su's latest patents is a bias circuit for a low noise amplifier of a front end interface of a radio frequency communication device. This invention enables fast transitions between different operating modes. The bias circuit includes a bias generator that provides a bias voltage on a bias node for the low noise amplifier. It features a first resistive device coupled between the bias node and an input of the low noise amplifier, along with a first switch that is coupled in parallel with the first resistive device. The mode control circuitry receives a mode signal indicative of a mode change and momentarily activates the first switch to bypass the first resistive device, thereby increasing the current capacity of the bias generator. Additionally, the mode control circuitry may also momentarily activate a second switch to bypass a second resistive device of the bias circuit.
Another notable patent is for a low power, efficient Doherty power amplifier. This apparatus includes a digital baseband circuit that receives a digital baseband signal and outputs a first and a second digital baseband signal. The second digital baseband signal is a scaled version of the first. The invention also features two transmitter signal paths, each processing the respective digital baseband signals and outputting amplified radio frequency signals.
