Document Type and Number:
Japanese Patent JPH0311038
Kind Code:
B2
Abstract:
A leakage current between the inverting input terminal and the output terminal of an operational amplifier having a switch between the two terminals is prevented from flowing by equalizing the potentials at the two terminals of the switch when it is open. This is accomplished by dividing the switch into two and inserting an additional switch between the intermediate node of the divided two switches and a reference potential point.
