APPARATUS AND METHODS FOR MEASUREMENT OF ANALOG VOLTAGES IN AN INTEGRATED CIRCUIT |
摘要 |
The present disclosure relates to apparatus and methods for measurement of analog voltages in an integrated circuit. In particular, the apparatus includes an on-chip digital-to-analog converter configured to receive a variable digital input code and output a corresponding analog voltage corresponding to the variable digital input code. The apparatus also includes an on-chip comparator circuit configured to receive the analog voltage output by the digital-to-analog converter and a test analog voltage as inputs and to provide an output indicating the test analog voltage. Further, the apparatus includes an on-chip logic operative to determine the test analog voltage based on the output of the comparator circuit. A corresponding method is also disclosed. |
