What is the difference between the different modes of operation?
The primary difference lies in the intended user environment. There are numerous modes of circuit operation of these devices. A few of the different modes are: 13. N-Channel Zero Threshold Mode The Zero Threshold MOSFET is an EPAD MOSFET Array where the individual threshold voltage of each MOSFET is fixed at zero. These devices are unique by using ALD EPAD technology to offer very low voltage switching with sharp turn-off and very low leakage characteristics similar to that for a conventional MOSFET. The zero threshold voltage is defined as Ids =1uA @ Vds=0.1V when the gate voltage Vgs=0.00V. 14. N-Channel Enhancement Mode The ALD1108xx/ALD1109xx products are enhancement mode EPAD MOSFET devices, which require a positive bias voltage to turn on. Precision threshold values such as +1.50V, +0.80V, +0.40V and +0.20V are offered as standard products. 15. N-Channel Depletion Mode ALD1148xx/ALD1149xx products are depletion mode EPAD MOSFETs, which are normally-on devices when the gate bias v
