Publication number: 20240133925Abstract: Embodiments herein relate to a circuit for evaluating the ground voltage of each circuit partition of a number of circuit partitions, one partition at a time. Once the ground voltage is determined, a corresponding code is stored to control a leakage circuit coupled to the ground node. The leakage circuit provides a leakage current based on the code to offset the ground voltage to a target voltage, which may be common for each of the partitions. The circuit can include a voltage source which supplies a stair step increasing voltage to a comparator. The comparator compares the voltage of the voltage source to the ground node voltage and provides an output which changes when the two input voltages are approximately equal, within a tolerance. The circuit may include a finite state machine for managing the process.Type: ApplicationFiled: October 23, 2022Publication date: April 25, 2024Inventors: Chia How Low, Roger Cheng

Patent number: 9495002Abstract: Embodiments include apparatuses, methods, and systems for providing a dynamic bias voltage to one or more transistors of a transceiver. In embodiments, a transceiver includes receive circuitry and transmit circuitry coupled to a same input/output (I/O) pad. A dynamic biasing circuit detects a voltage level of a data signal on the I/O pad, and generates a dynamic bias voltage having a value based on the detected voltage level. In some embodiments, the dynamic bias voltage is a selected one of a first bias voltage or a second bias voltage. The dynamic biasing circuit provides the dynamic bias voltage to one or more transistors of the transceiver to protect the transistors from electrical overstress.Type: GrantFiled: May 5, 2014Date of Patent: November 15, 2016Assignee: Intel CorporationInventor: Chia How Low
