WebMar 25, 2024 · To achieve high accuracy, dynamic element matching is often applied to cancel the mismatch between BJTs and the current sources. To avoid complex logic, the ratios ( p and r ) should be kept small. In most BJT sensors, p ∙ r is between 2 and 10. http://ispg.ucsd.edu/wordpress/wp-content/uploads/2024/05/2010-TCASII-I.-Galton-Why-Dynamic-Element-Matching-DACs-Work.pdf
