Claim 0:
1. A voltage conversion method adapted to deliver to a load a regulated voltage, VReg, said method comprising the steps of:
developing a first tuning parameter and a second tuning parameter, said first tuning parameter being developed as a function of a process corner, and said second tuning parameter adjusts a complementary-to-absolute temperature coefficient of a sub-threshold regulated voltage, VSub, wherein VSub is less than a selected transistor threshold voltage, Vth;
storing said first tuning parameter and said second tuning parameter;
developing a reference voltage, VRef, as a function of said first tuning parameter;
developing said sub-threshold regulated voltage, VSub, as a function of said second tuning parameter and of said reference voltage, VRef; and
selecting as said regulated voltage, VReg, said sub-threshold regulated voltage, VSub.
