Methods and apparatus for current sensing |
摘要 |
Methods and apparatus for current sensing according to various aspects of the present invention sense the current in a circuit, such as an inductor circuit. The current sensing systems may comprise an RC element connected such that the RC time constant matches the L/R time constant of the inductor. The current sensor may be configured to generate voltages that are proportional to the instantaneous current in the inductor with scaled gain for a wide range of inductor self resistance (DCR) values. |
