Abstract: An adaptive current mirror circuit for current shaping with temperature is disclosed. The adaptive current mirror includes a current generator circuit configured to receive and input current and generate an output current using the input current and an overdrive voltage. The adaptive current mirror further includes a compensation circuit configured to adjust a value of the overdrive voltage based on temperature.
