Abstract
An electronic device includes a bandgap reference voltage generation stage. The bandgap reference voltage generation stage comprises a device with a PN-junction, a current source feeding a first current during a first period of time and a second higher current during a second period of time through the PN-junction. The bandgap reference voltage is generated from a combination of a first voltage drop across the PN-junction during the first period of time and a second voltage drop across the PN-junction during the second period of time. This bandgap reference voltage is formed using switched capacitors.
