GENERAL DESCRIPTION
The ALD210802 precision enhancement mode N-Channel EPAD® MOSFET
array is precision matched at the factory using ALD’s proven EPAD® CMOS
technology. These quad monolithic devices are enhanced additions to the
ALD110802 EPAD® MOSFET Family, with increased forward transconductance
and output conductance, particularly at very low supply voltages.
Intended for low voltage, low power small signal applications, the ALD210802
features precision threshold voltage, which enables circuit designs with input/
output signals referenced to GND at enhanced operating voltage ranges. With
these devices, a circuit with multiple cascading stages can be built to operate at
extremely low supply/bias voltage levels. For example, a nanopower input amplifier
stage operating at less than 0.2V supply voltage has been successfully
built with these devices.
ALD210802 EPAD MOSFETs feature exceptional matched pair electrical characteristics
of Gate Threshold Voltage VGS(th) set precisely at +0.20V +0.020V,
IDS = +10μA @ VDS = 0.10V, with a typical offset voltage of only +0.002V (2mV).
Built on a single monolithic chip, they also exhibit excellent temperature tracking
characteristics. These precision devices are versatile as design components
for a broad range of analog small signal applications such as basic building
blocks for current mirrors, matching circuits, current sources, differential amplifier
input stages, transmission gates, and multiplexers. They also excel in limited
operating voltage applications, such as very low level voltage-clamps and
nano-power normally-on circuits.
In addition to precision matched-pair electrical characteristics, each individual
EPAD MOSFET also exhibits well controlled manufacturing characteristics, enabling
the user to depend on tight design limits from different production batches.
These devices are built for minimum offset voltage and differential thermal response,
and they can be used for switching and amplifying applications in +0.1V
to +10V (+0.05V to +5V) powered systems where low input bias current, low
input capacitance, and fast switching speed are desired. At VGS > +0.20V, the
device exhibits enhancement mode characteristics whereas at VGS < +0.20V
the device operates in the subthreshold voltage region and exhibits conventional
sub threshold characteristics, with well controlled turn-off and sub-threshold
levels that operate the same as standard enhancement mode MOSFETs.
The ALD210802 features high input impedance (2.5 x 1010Ω) and high DC current
gain (>108). A sample calculation of the DC current gain at a drain output
current of 30mA and input current of 300pA at 25°C is 30mA/300pA
100,000,000, which translates into a dynamic operating current range of about
eight orders of magnitude. A series of four graphs titled “Forward Transfer Characteristics”,
with the 2nd and 3rd sub-titled “expanded (subthreshold)” and “further
expanded (subthreshold)”, and the 4th sub-titled “low voltage”, illustrates
the wide dynamic operating range of these devices.
Generally it is recommended that the V+ pin be connected to the most positive
voltage and the V- and IC (internally-connected) pins to the most negative voltage
in the system. All other pins must have voltages within these voltage limits
at all times. Standard ESD protection facilities and handling procedures for static
sensitive devices are highly recommended when using these devices.
