  • Publication number: 20240143007
    Abstract: A voltage regulator includes an input power supply node, an output regulated power supply node, a flipped voltage follower circuit, and a compensation capacitor. The flipped voltage follower circuit includes an output transistor configured as a common-source amplifier circuit. A source terminal of the output transistor is coupled to the input power supply node and a drain terminal of the output transistor is coupled to the output regulated power supply node. The flipped voltage follower circuit includes a folded cascode feedback circuit. The folded cascode feedback circuit includes a folding node. The folded cascode feedback circuit is configured to receive an output regulated voltage on the output regulated power supply node and to provide a feedback signal to a gate terminal of the output transistor. The compensation capacitor is coupled to the output regulated power supply node and the folding node.

  • Patent number: 11626874
    Abstract: Systems, apparatuses, and methods for conveying and receiving information as electrical signals in a computing system are disclosed. A computing system includes multiple transmitters sending singled-ended data signals to multiple receivers. A termination voltage is generated and sent to the multiple receivers. The termination voltage is coupled to each of signal termination circuitry and signal sampling circuitry within each of the multiple receivers. Any change in the termination voltage affects the termination circuitry and affects comparisons performed by the sampling circuitry. Received signals are reconstructed at the receivers using the received signals, the signal termination circuitry and the signal sampling circuitry.
