Abstract
A shunt regulator for the programming voltage of programmable circuit devices employs components formed of the same layers that make up the regulated devices, including the same tunnel structure (52) of floating gate devices that are being regulated. A transistor (66) connected as a load on the programming voltage line (10) is itself controlled by tunneling structure (52) and capacitors (18, 20) formed by layers corresponding to layers of the regulated devices so that variations in the regulator components will track variations of the regulated components to automatically compensate for manufacturing process variations.
