Latest Patents

Yerramilli's latest patents include a wideband coupled input impedance matching LNA architecture. This invention focuses on circuits and methods for RF amplifiers, such as low-noise amplifiers (LNAs), that incorporate a wideband coupled input impedance matching network. One embodiment features a first inductor connected between a first terminal and a first node, which is couplable to a degeneration terminal of an amplifier core. Additionally, a second inductor is coupled between a second terminal and either the first node or a second node, with the second terminal couplable to an input terminal of the amplifier core. A third inductor is also included, coupled between the first node and a third terminal, which is couplable to a reference potential. In a variant embodiment, a fourth inductor is coupled between the second node and a fourth terminal, also couplable to the reference potential. This design allows for multiple modes, enabling trade-offs between gain, linearity, and noise figure characteristics.

Another notable patent involves phase shift matching for multi-path amplifiers. This invention presents methods and devices aimed at minimizing phase discontinuity between different gain modes, including bypass, active, and passive modes. The design reduces the increase in circuit size and complexity without compromising other performance parameters. The phase shifter elements can be integrated into both active and passive bypass paths, enhancing the versatility of RF receiver front-ends.
