METHOD FOR SHIFTING AN AUTO-ZERO VOLTAGE IN AN ANALOG COMPARATOR

摘要

PURPOSE: A method for shifting an auto-zero voltage in an analog comparator is provided to reduce noise or another signal offset which includes a converted digital signal.;CONSTITUTION: At least one transistor increases a drain voltage of at least one load transistor by diodes. A first switch(SW401) increases a voltage in the gate of a first input transistor by a diode voltage. The diode voltage corresponds to at least one transistor when the first switch is closed. A second switch(SW402) increases a voltage in the gate of a second input transistor by the diode voltage. The diode voltage corresponds to at least one transistor when the second switch is closed.;COPYRIGHT KIPO 2012
