Function description

High precision low temperature co-efficiency reference voltage is applied to the negative input of a

comparator. Input voltage, divided by resistor array of Ra and Rb, is applied to the positive input of the

comparator. Output of the comparator passes a delay circuit and a series of buffer to drive the output

CMOS pair.
