... device. The terminals of the device are the gate, source, drain, and substrate. There are two types of mosfets: the enhancement type and the depletion type. In the enhancement type MOSFET, the ... the source and drain has to be induced by applying a voltage on the gate. In the depletion type mosfet, the structure of the device is such that there exists a channel between the source and ... will be done using an enhancement-type mosfet. In the latter device, the channel between the drain and source has to be induced by applying a voltage between the gate and source. The voltage...
