Analog circuit designs that use inverting opamp configuration can be converted into low-voltage designs by biasing the opamp input common-mode voltage to near one of the supply rails. This is achieved by introducing a current source or a resistor between the opamp negative input terminal and one of the supply rails. Hence, in this technique, opamps with limited input common-mode range can be used. In addition, switches can be incorporated in these circuits to allow a wide range of applications… Expand
