Latest Patents
One of Haopei Deng's latest patents focuses on "Transistor bias adjustment for optimization of third order intercept point in a cascode amplifier." This invention describes methods and devices for amplifying an input RF signal according to at least two gain states. A multi-gain amplifier circuit, which includes a low noise amplifier with a stack of transistors, is utilized for the amplification process. When transitioning from a low gain state to a high gain state, the drain-to-source voltage of the output transistor is increased to optimize its operational region, thereby reducing non-linearity at the amplifier's output. Conversely, when switching from a high gain state to a low gain state, the drain-to-source voltage of the input transistor is adjusted to achieve similar non-linearity reduction.
