Abstract:
An improved semiconductor integrated circuit comprising a substrate, at least one first semiconductor resistor, and at least one second semiconductor resistor, with the the first and second resistors defining a resistance ratio, and a bootstrap electrode at a desired potential, wherein variation in resistance value of the first resistor is determined by the potential difference between the first resistor and the substrate, and variation in resistance value of the second resistor is determined by the potential at the boot-strap electrode, and wherein the variation in the resistance value of the second resistor acts to cancel out the variation in the first resistor resistance value, whereby an accurate device is produced by the invention.
