This paper presents a class of novel, high-order, A-stable defect correction schemes. These schemes are grounded in a newly developed, more versatile class of BDF approaches, which utilize Taylor expansions at time tn+β with β > 1 being an adjustable parameter. The ranges for the stability parameters of these newly proposed defect correction schemes are specified to ensure A-stability. Additionally, numerical experiments are given to illustrate the precision and robustness of the schemes when addressing stiff problems.
