The present disclosure relates to a method of controlling an analog-to-digital converter, wherein a most significant bit is determined by implementing successive approximation of a first digital-to-analog converter and a second digital-to-analog converter. Further, the least significant bits are determined by time-to-digital conversion by applying a first ramp to the output of the first converter with a third digital-to-analog converter and by applying a second ramp to the output of the second converter with a fourth digital-to-analog converter. The direction of change of the first ramp and the second ramp is determined by comparing the outputs of the first converter and the second converter at the end of the successive approximation. 本公开涉及一种控制模数转换器的方法，其中通过实现第一数模转换器和第二数模转换器的逐次逼近来确定最高有效位。另外，通过用第三数模转换器将第一斜坡施加到第一转换器的输出并通过用第四数模转换器将第二斜坡施加到第二转换器的输出，通过时间到数字转换来确定最低有效位。第一斜坡和第二斜坡的变化方向通过在逐次逼近结束时第一转换器与第二转换器的输出的比较来确定。
