Latest Patents

Chettan Babla holds a patent for an "Image reject mixer, circuit, and method for image rejection." This invention aims to reduce the impact of image frequencies generated by mixing an incident carrier signal down to a relatively low intermediate frequency signal used in subsequent signal processing. The mixing frequency is selected to ensure that the generated intermediate frequency signal has a frequency offset relative to DC that aligns with the single channel spacing between frequency-adjacent incident carrier signals. Furthermore, the integration of a current-driven polyphase filter directly between the input stage and the mixer stage enhances image rejection by mitigating quadrature divergence within the image reject mixer.
