In one embodiment, a receiver comprises a sample latch having a first input coupled to a receive data path, and a second input. The receive also comprises a first digital-to-analog converter (DAC), a second DAC, and a calibration controller. In a calibration mode, the calibration controller is configured to input a calibration voltage to the first input of the sample latch using the first DAC, to input a threshold voltage and an offset-cancelation voltage to the second input of the sample latch using the second DAC, to adjust the offset-cancelation voltage, to observe an output of the sample latch as the offset-cancelation voltage is adjusted, and to store a value of the offset-cancelation voltage at which a metastable state is observed at the output of the sample latch in a memory."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Offset calibration for low power and high performance receiver","description":"Systems and methods for providing offset calibration for low power and high performance receivers are described herein.
