  • Patent number: 12111350
    Abstract: An on-chip or built-in self-test (BIST) module for an RFIC is provided. The BIST module can be implemented in an RFIC system, which may include a beamforming module of a radar system. The BIST module may include components and methods to up-convert a signal from a test frequency to RF at an input to the RFIC and down-convert and output signal.

  • Publication number: 20240322776
    Abstract: A variable gain amplifier is disclosed having parallel sets of transistors and control for bias voltages, wherein the average of bias voltage values is strategically controlled to reduce phase variance. For example, a variable gain amplifier may include a first set of transistors coupled to a first bias voltage, a second set of transistors coupled to a second bias voltage, where the second set of transistors is coupled in parallel with the first set of transistors, and a control module adapted to control the first and second bias voltages, the control module adapted to reduce the gain of the first set of transistors while increasing the gain of the second set of transistors.
