Assignee: AMBIQ MICRO, INC.
Field: Computer technology (Electrical engineering)
Classification: CPC G  H  Y | IPC G  H

Claim 20:
21. A method for use during the manufacture and operation of an integrated circuit for developing a regulated voltage, Vdd, wherein Vdd is less than a selected transistor threshold voltage, Vth, said method comprising the steps of:
during the manufacture of the integrated circuit:
developing a first tuning parameter as a function of a selected process corner;
developing a second tuning parameter as a function complementary to absolute temperature; and
storing said first and second tuning parameters; and

during the operation of the integrated circuit:
loading said first and second tuning parameters;
developing a reference voltage, VRef, as a function of said loaded first tuning parameter; and
developing said regulated voltage, Vdd, as a function of said loaded second tuning parameter and of said reference voltage, VRef.
