Application: Active filter (Patent ID: US20230421133A1)

The patent filed by Renesas Electronics Corp describes an active filter that includes an operational amplifier and a controller that can adjust the bandwidth of the operational amplifier based on settings for filter cutoff frequency and noise performance. The active filter can be tuned using variable resistors to set the cutoff frequency based on the filter cutoff frequency setting received by a filter decoder. Additionally, the controller can set the gain bandwidth product of the operational amplifier to a value that ensures the noise performance is below a specified threshold.

Furthermore, the patent details a method for controlling the active filter by adjusting the bandwidth of the operational amplifier based on the filter cutoff frequency setting and/or noise performance setting using the controller. The patent also extends to an apparatus, such as an amplifier or analog to digital converter, that incorporates the active filter and controller to regulate the operational amplifier's bandwidth based on the filter cutoff frequency and noise performance settings. The apparatus can switch between high performance and low power modes depending on the noise performance setting relative to a threshold value, showcasing the versatility and adaptability of the active filter system.
