| 摘要 |
A linear voltage amplifier circuit which utilizes a plurality of field-effect devices having substantially identical operating characteristics. The devices are connected in a series arrangement with the source electrode of each device coupled to the drain electrode of its adjacent device. Each of the devices except one selected device has its gate electrode coupled to its drain electrode. An input terminal is coupled to the gate electrode of the selected device and an output terminal is connected to the drain electrode of one of the devices. In a preferred embodiment of the invention the gain of the amplifier is -(n-1) where n equals the number of devices in the series arrangement.
