FUNCTIONAL DIAGRAM
FUNCTIONAL DESCRIPTION
The ZNBG devices provide all the bias requirements for external FETs, including the generation of the negative
supply required for gate biasing, from the single supply voltage.The diagram above shows a single stage from
the ZNBG series. The ZNBG3115/16 contains 3 such stages. The negative rail generator is common to both
devices.
The drain voltage of the external FET Q
N
is set by the ZNBG device to its normal operating voltage. This is
determined by the on board V
D
Set reference, for the ZNBG3115 this is nominally 2.2 volts whilst the ZNBG3116
provides nominally 2 volts.
ThedraincurrenttakenbytheFETismonitoredbythelowvalueresistorIDSense.Theamplifierdrivingthegate
of the FET adjusts the gate voltage of Q
N
so that the drain current taken matches the current called for by an
external resistor R

to obtain the required drain current. To provide this capability powered from a single positive supply, the device
includes a low current negative supply generator. This generator uses an internal oscillator and two external
capacitors, C

and C
