VOLTAGE REFERENCE
Reference Biasing
The voltage reference is of a shunt regulator topology that
models as a simple zener diode. With current I
flowing in the
‘forward’ direction there is the familiar diode transfer func-
tion. I
flowing in the reverse direction forces the reference
voltage to be developed from cathode to anode. The applied
voltage to the cathode may range from a diode drop below
V
to the reference voltage or to the avalanche voltage of the
parallel protection diode, nominally 7V.A6.3V reference with
V+ = 3V is allowed.
