<p>A current-sensing rectifier for current rectification and measurement applications is described. The current-sensing rectifier comprises a current-sensing device (100) for rectifying the current in a selected circuit branch and an active-sense comparison circuit (140) to measure the sense current provided by the current-sensing device. The current-sensing device and active measurement circuit are operated such that the current-sensing device rectifies the current of a selected circuit branch. No negative voltage supplies are required for rectification or for the measurement of the branch current. Further embodiments of the present invention include sample-and-hold circuits which sample the value of the rectified current during an ON-period of operation and maintain the sampled value during a subsequent OFF-period.</p> |
