Driving circuit with charge sharing and multiple output stages
The patent US12047074B2 describes a sophisticated driving circuit designed to manage multiple output voltages with distinct polarities and functionalities. The circuit comprises two primary output stage circuits, each configured to output different voltages of varying polarities. It includes a series of switches and charge sharing circuits that facilitate the transfer and sharing of charge between multiple output channels. Specifically, the first and second output stage circuits generate voltages of a first polarity, while the third and fourth output stage circuits produce voltages of a second polarity, which is distinct from the first. The design allows for controlled switching between these voltages, enabling efficient operation across different output channels.
Additionally, the claims detail the operational conditions of the charge sharing circuits and switches. For instance, when the first charge sharing circuit is activated, the corresponding switches are turned off, ensuring that the first and second output channels can share charge effectively. The patent also specifies configurations for when the charge sharing circuits are inactive, allowing the switches to directly provide their respective voltages to the output channels. Furthermore, the circuit is structured to accommodate both odd-numbered and even-numbered output channels, enhancing its versatility in various applications. Overall, this driving circuit presents a novel approach to voltage management in electronic systems, emphasizing efficiency and adaptability.
