Abstract:
An integrated circuit includes a voltage reference circuit including a Zener diode having a first terminal coupled to a first node and a second terminal coupled to a first voltage supply terminal. A proportional to absolute temperature (PTAT) circuit is coupled at the first node and configured to generate a PTAT current. A PTAT compensation circuit is coupled at the first node. The PTAT compensation circuit includes a first current mirror having a first branch coupled at the first node.

Claim (Index 16):
A semiconductor device comprising:\n a Zener diode-coupled between a first node-and a first voltage supply terminal; a PTAT circuit coupled at the first node, the PTAT current establishing a PTAT voltage across a first resistor coupled at the first node to generate a proportional to absolute temperature (PTAT) current; and a PTAT compensation circuit coupled at the first node to inject a PTAT compensation current at the first node, the PTAT compensation circuit comprising:\n a first transistor having a first current electrode coupled to a second voltage supply terminal and a second current electrode coupled at the first node; and \n a second transistor having a first current electrode coupled to the second voltage supply terminal and a second current electrode coupled to control electrodes of the first and second transistors; and \n a third transistor having a first current electrode coupled to the second current electrode of the second transistor, a control electrode coupled to the PTAT circuit, and a second current electrode coupled to the first voltage supply terminal.
