用于切换电路和切换放大器的停滞时间电路;A DEAD TIME CIRCUIT FOR A SWITCHING CIRCUIT AND A SWITCHING AMPLIFIER

摘要

揭示一种用于一切换电路之停滞时间电路(750)。该停滞时间电路包含：一输入端(752)，用于接收该切换电路之一切换信号，该切换电路具有至少一供电轨线，而该至少一供电轨线具有一接地弹跳信号；第一与第二输出端(754a、754b)；一第一前馈路径(756)，耦接至该第一输出端并被配置以接收该切换信号；一第二前馈路径(758)，耦接至该第二输出端并被配置以接收该切换信号；一第一反馈路径(760)，在该第一输出端与该第二前馈路径之间形成一第一反馈回路；以及一第二反馈路径(762)，在该第二输出端与该第一前馈路径之间形成一第二反馈回路；其中该第一与第二前馈路径各自均包含一各别第一与第二延迟电路(764a、764b)，而该第一与第二延迟电路(764a、764b)各自均具有一大于该接地弹跳信号之一特定时间长度之时间延迟。其亦揭示一种切换放大器。; first and second outputs (754a, 754b); a first feedforward path (756) coupled to the first output and arranged to receive the switching signal; a second feedforward path (758) coupled to the second output and arranged to receive the switching signal; a first feedback path (760) forming a first feedback loop between the first output and the second feedforward path; and a second feedback path (762) forming a second feedback loop between the second output and the first feedforward path; wherein each of the first and second feedforward paths includes a respective first and second delay circuit (764a, 764b), each having a time delay greater than a predetermined time period of the ground bounce signal. A switching amplifier is also disclosed.
