Latest Patents

One of her latest patents is focused on a subsampling RF receiver architecture. This invention is designed for converting an RF signal to baseband and can be implemented in wireless communication devices, such as mobile handsets. The receiver includes a sample and hold circuit that samples a bandpass filtered input modulated signal at a subsampling frequency that is well below the RF carrier frequency but twice the bandwidth of the payload. The sampled signal is then digitized and processed through two digital mixers to produce in-phase and quadrature components of the payload. In another embodiment, the receiver features two sample and hold circuits to sample the filtered signal at different phases, enhancing the digital component production. Additionally, a third embodiment incorporates an analog mixer to downconvert the RF input to an intermediate frequency before digitization.

Another significant patent by Chan is a generic line impedance matching circuit that utilizes decomposed configurable transfer functions. This innovative technique allows for the implementation of impedance matching circuits that can accommodate a diverse range of line impedances by simply adjusting coefficients, thus reusing the same circuit topology.
