Claim 17:
18. The method of claim 11, wherein determining the scale setting comprises:
determining the scale setting of the plurality of programmable scale settings that configured the programmable PTAT generator to generate an output current having the predetermined temperature coefficient comprises calculating:

m=([(TH−TL)*SD−IPTAT_H_MIN+IPTAT_C_MIN]*NSTEPS)/[(IPTAT_H_MAX−IPTAT_H_MIN)−(IPTAT_C_MAX−IPTAT_C_MIN)],, where m is the determined scale setting of the plurality of programmable scale settings, TH is the first temperature, TL is the second temperature, SD is the predetermined temperature coefficient, NSTEPS is a number of the programmable scale settings, IPTAT_H_MAX is the first current measurement, IPTAT_H_MIN is the second current measurement, IPTAT_C_MAX is the third current measurement, and IPTAT_C_MIN is the fourth current measurement.
