The diagrams below show partial application circuits for the ZNBG series showing all external components
requiredforappropriatebiasing.Thebiascircuitsareunconditionallystableoverthefulltemperaturerangewith
the associated FETs and gate and drain capacitors in circuit.
To minimise board space the ZNBG3115/3116 is offered in a QSOP16 package. To reduce the pin count Drain 1
andDrain2havebeeninternallyconnected.Thisispossiblebecauseonlyoneofthetwobiasstagescanbiasedat
one time.The QSOP16 offers a 40% reduction in size over the QSOP20 version.
Capacitors C2 and C4 ensure that residual power supply and substrate generator noise is not allowed to affect
other external circuits which may be sensitive to RF interference. They also serve to suppress any potential RF
feedthrough between stages via the ZNBG device. These capacitors are required for all stages used. Values of
10nF and 4.7nF respectively are
recommended however this is design
dependentandanyvaluebetween1nF
and 100nF could be used.
The capacitors C
NB
and C
SUB
are an
integral part of the ZNBGs negative
supply generator. The negative bias
voltage is generated on-chip using an
internal oscillator. The required value
of capacitors C
NB
and C
SUB
is 47nF.
This generator produces a low current
supply of approximately -3 volts.
Although this generator is intended
purely to bias the external FETs, it can
be used to power other external
circuits via the C
SUB
pin.
Resistor R
sets the drain current at
whichallexternalFETsareoperated.If
any biascontrolcircuitisnotrequired,
its related drain and gate connections
may be left open circuit without
affecting the operation of the
remaining bias circuits.
The ZNBG devices have been
designed to protect the external FETs
from adverse operating conditions.
With a JFET connected to any bias
circuit, the gate output voltage of the
bias circuit can not exceed the range
-3.0V to 1V under any conditions,
including powerup and powerdown
transients. All the bias stages include
drain currents limits which work
independently in each stage. Should
thenegativebiasgeneratorbeshorted
or overloaded so that the drain current
of the external FETs can no longer be
controlled, the drain supply to FETs is
shut down to avoid damage to the
FETs by excessive drain current.
