Application: Reduction of artefacts in multi-channel systems (Patent ID: US20240204734A1)
The patent filed by Cirrus Logic Inc. describes circuitry for driving first and second loads, with sequencer circuitry controlling state changes in the output signal paths to prevent synchronization between the two. The circuitry includes DAC circuitry, amplifier circuitry, and a common ground path for the output signal paths, with the loads potentially being audio or haptic output transducers. The method outlined in the patent aims to reduce artifacts in a multi-channel system during state changes by ensuring asynchrony between channels.
The circuitry further includes clamp paths, and the sequencer circuitry manages the start-up and shut-down processes by enabling or disabling the output signal paths in a specific sequence to prevent synchronization of state changes. The patent also covers an integrated circuit and host devices like laptops, gaming consoles, mobile phones, and VR/AR devices that incorporate the described circuitry for driving loads. Overall, the invention aims to improve the performance and reliability of multi-channel systems by controlling the timing of state changes in different channels to minimize artifacts and ensure smooth operation.
