METHOD AND SYSTEM FOR AUTO-RANGING ANALOG-TO-DIGITAL CONVERTER FOR CURRENT SENSING |
摘要 |
Embodiments of the present disclosure provide a method and system for an auto-ranging analog-to-digital converter (ADC) for dynamically scaling inputs to an ADC. The auto-ranging ADC includes a dynamically configurable transistor arrangement for delivering a load current and a replica device for replicating the load current. A current sense resistor generates a replicated load voltage based on the replicated current. The ADC generates a digital value based on the replicated load voltage. The auto-ranging ADC also includes an auto-ranging controller for dynamically configuring the transistor arrangement based on the digital value to scale the inputs to the ADC.
