摘要： A current reference with reduced sensitivity to process variations includes a variable resistor and a control transistor. The control transistor has a generated current from source-to-drain that first passes through the variable resistor. The control transistor has a reference voltage applied to the gate, and the source-to-gate voltage is a function of the reference voltage and the voltage drop across the variable resistor. A control loop circuit measures the generated current and modifies the resistance value of the variable resistor in response. An external precision resistor is used to measure the generated current, and current variations as a result of process variations are reduced.

摘要： A current reference with reduced sensitivity to process variations includes two current sources. The first current source has an output current that is sensitive to process variations. The second current source has, as a component of its input current, the output current of the first current source. The input current to the second current source is substantially constant because the process dependent component has been removed by the output current of the first current source. Variable resistors internal to the current source are set using a control loop circuit and an external resistor.
