In one example, a system for driving a speaker includes an output stage configured to drive a current through the speaker. The system further includes a first and second current sensor coupled to the output stage and configured to measure a positive current including a first measurement error and a negative current including a second measurement error through the speaker, respectively. The system further includes a processing block coupled to the first and second current sensors to receive the measured positive and negative current signals and configured to add a positive offset value to an input of each first and second current sensors, determine the first and second measurement errors, and correct a measured current using the positive and negative currents and the determined first and second measurement errors."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Correction of current measurement in an amplifier","description":"Systems and methods according to one or more embodiments are provided for correcting a current measurement through a speaker in an audio system.
