VOLTAGE REFERENCE

Reference Biasing

The voltage reference is of a shunt regulator topology that

models as a simple zener diode. With current I

r flowing in the

‘forward’ direction there is the familiar diode transfer func-

tion. I

r 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

− to the reference voltage or to the avalanche voltage of the

parallel protection diode, nominally 7V. A 6.3V reference with

V+ = 3V is allowed.
