Methods and circuits for adjusting the output parameter of a device wherein the output parameter is temperature dependent are disclosed herein. An example of a method includes: adjusting the output parameter to a target level at a first temperature; adjusting a linear temperature-dependent variable related to the output parameter to zero at the first temperature; adjusting a nonlinear temperature-dependent variable related to the output parameter to zero at the first temperature; adjusting the output parameter to the target level at a second temperature using the linear-dependent variable; adjusting the nonlinear temperature-dependent variable to zero at the second temperature; and adjusting the output parameter to the target level at a third temperature by adjusting the nonlinear variable.
