Latest Patents

One of Wang's latest patents is a low noise amplifier topology. This innovative design achieves a very low noise figure by applying multiple magnetic couplings between gate matching inductors and a source degeneration inductor of a field effect transistor. The resulting low noise amplifier features smaller inductors, which contribute to lower thermal noise and maintain excellent gain and linearity performance. For instance, the design includes a first inductor to receive an input, a second inductor coupled to the first inductor in series, a first field effect transistor device whose gate receives a signal from the second inductor, and a third inductor coupled to the source of the first field effect transistor device, where the third inductor is magnetically positively coupled to the first and second inductors.

Another notable patent is related to active balun design. This patent describes an active balun circuit that includes a plurality of transistors, an output transmission line connected to the output terminals of the transistors, an input transmission line, and a series of capacitors coupled to the input terminal of the transistors and the input transmission line.
