Patent ID: 7902907

Claim:
An integrated circuit comprising: a first plurality of diffused resistors arranged in series for a voltage divider, the voltage divider comprising: an output node; an input node coupled to an input voltage; and a reference node coupled to a voltage reference; a first diffused resistor having a first terminal and a second terminal, wherein the first diffused resistor is of a first semiconductor type and is disposed in a first well of a second semiconductor type, wherein the first terminal is coupled to the output node and wherein the second terminal of the first diffused resistor is coupled to the reference node; a second plurality of diffused resistors arranged in series between the input node and the output node, wherein each of the second plurality of diffused resistors is of the first semiconductor type and is disposed in its own well of the second semiconductor type, wherein the second plurality of diffused resistors consists of each resistor arranged in series between the input node and the output node; and a plurality of explicit capacitors arranged in series, wherein each of the plurality of explicit capacitors is coupled directly in parallel with a respective one of each diffused resistor of the second plurality of diffused resistors; wherein there is not an explicit capacitor in parallel with the first diffused resistor.
