Patent ID: 6930540

Claim:
An integrated circuit, comprising: a voltage divider having a series circuit formed with a first resistor and a second resistor connected between a voltage output line and a potential sink or potential source, and a node between said first resistor and said second resistor; an activation circuit for selectively connecting and disconnecting said series circuit between the voltage output line and the potential sink or potential source, said activation circuit comprising a first switch connected between an output of said first resistor and said node, and a second switch connected between said second resistor and said potential sink or potential source; a capacitor connected in parallel with said first resistor, said capacitor having a first terminal connected to an input of said first resistor and a second terminal connected to said node between said first resistor and said second resistor; and a further resistor connected in series with said second resistor and in parallel with said second switch and between said node and said potential sink or potential source, said further resistor enabling a voltage supply for said capacitor when said first switch and said second switch are disconnected and said series circuit of said voltage divider is not directly connected between the voltage output line and the potential sink or potential source.
