  • Differential amplifier
    Patent number: 5210236
    Abstract: A differential amplifier has a pair of inputs and a pair of outputs. Each of the outputs is connected between a high potential source and a low potential source through a pair of FETs, respectively. These FETs have the same conduction type. A gate of one of the FETs is connected to one of the inputs, and a gate of the other FET is connected to the other input. This arrangement suppresses output offset and realizes a wide sensitivity range.
